Chapter 102 Deification of Electrolyzed Water

When Chen Xingyang saw Yu Fan came back, he knew that Yu Fan should have a plan in his heart.He also showed his police badge and shouted: "Police!"

Everyone was stunned. When the crowd saw the police coming out, they knew that there was a good show to watch, and more and more people gathered to watch.

Yu Fan walked forward slowly, and the crowd consciously gave way to Yu Fan.

Guo Na also followed Yu Fan, and asked softly, "Brother Yu, where did you go just now?"

Yu Fan smiled and said to Guo Na: "Oh, I just went to the supermarket here to see if the price of pork is expensive. I bought something by the way, maybe I can use it." Throw it on the table for the water quality experiment.

The man with glasses was not panicked at all. With a flattering smile on his face, he said to Chen Xingyang: "Comrade policeman, you may have misunderstood. We are a regular company, not a liar." As he spoke, the assistant next to him took out a stack of Show the data to Chen Xingyang.

Chen Xingyang was upright, took the information, threw it on the table, and said to the man with glasses mockingly: "Don't worry about this, you should see what the real experts say first." Chen Xingyang ordered one for Yu Fan. head, indicating that he may begin.

Yu Fan took two steps back, so that more people on the periphery of the crowd could see him.Yu Fan said: "In fact, from the very beginning, this is an out-and-out scam! Let me talk about the TDS measuring pen at the beginning. TDS is the abbreviation of Total Dissolved Solids in English, which actually means (water containing minerals) ) total dissolved concentration, that is, the total salts dissolved in water, so the level of 'TDS value' does not represent the quality of water, it is not an instrument for measuring water quality at all."

The crowd was in an uproar, whispering to each other. At this time, someone asked: "But we did see that our tap water became dirty, but the water they purified was not dirty. This is true. How is this?" What's going on?"

Yu Fan smiled slightly, and said to everyone: "This is actually not a problem with your water, but a problem with this instrument. This instrument is not a water quality tester, but an ordinary water quality electrolysis instrument."

The man with glasses realized that his behavior might have been exposed, so he moved back quietly, trying to escape in the crowd. Chen Xingyang had sharp eyes and saw it, but he said very calmly: "Glasses, don't try to run, you think the crowd will make you run away." Are you running? You'd better stay closer to me, lest the crowd get angry and kill you, and I won't have time to protect you." The man with glasses was frightened and stayed where he was, not daring to move.

Yu Fan continued to give everyone popular science: "The water quality electrolysis instrument has two sets of electrodes, each set of electrodes is composed of iron rods and aluminum rods. When doing experiments, put the electrodes into tap water and pure water respectively. The pure water has not changed much. At this time, the swindlers with glasses explained to everyone that these colored substances are harmful substances such as "pesticides", "viruses" and "heavy metals" in order to promote their water purifiers. But the real situation In fact, ordinary tap water must contain calcium and magnesium ions. Calcium and magnesium ions are electrolytes. After the iron rod of the anode of the electrolysis instrument is placed in tap water, the iron will be electrolyzed to form iron hydroxide (gray), ferrous ions (green), Ferric oxide (reddish brown) and ferric oxide (black); pure water does not contain conductive calcium and magnesium ions, and no electrolytic reaction occurs, so pure water does not change color."

The masses seem to understand but don't understand. After all, people who understand this kind of professional knowledge need a certain level of education, but Yu Fan has long been prepared for this situation.

Yu Fan: "In order to let everyone understand the reason, I bought a pack of salt from the small supermarket next to you. Everyone knows that salt is eaten every day and is not poisonous. I added it to the water they have just purified and does not change color. How about a little salt and a 'test' of the water quality?"

Yu Fan sprinkled a little salt in the water purified by their water purifier, then inserted the two metal rods of the water quality electrolysis instrument into it, and turned on the electricity. Not long after, the water that was still clear and transparent just now became turbid. , even dirtier than the results of the tap water test just now.

The onlookers suddenly realized that they had been cheated.

Yu Fan continued to explain this phenomenon: "Just now, it was the fairy water that can cure any disease. How could it become 'poison' water after adding a little salt? Because when salt dissolves in water, there will be a lot of conductive sodium and chloride ions. , This will promote the occurrence of electrolytic reaction. There will also be the phenomenon of water turning black. Therefore, fundamentally speaking, this group of people is a group of outright liars. Everything has a degree, and pure water is not necessarily better than pure water. Our tap water is good, and proper calcium and magnesium ions are actually helpful to the human body. And I can say with certainty that the water purifiers sold to you by these people are completely fooled by you.”

When Yu Fan started deciphering just now, Guo Na had already contacted the local police, and the local police arrived very quickly, just in time, and the trio of men with glasses had no choice but to arrest them without a fight.

Back at the police station, Chen Xingyang communicated with the local police officers and briefly introduced the ins and outs. Police officer Ziyi also communicated with the police in Tashui Town about this matter in advance, so they also understood the situation in advance.Chen Zhuangyang hoped to interrogate these three people alone and find clues about Chen Taizhou, because from the current point of view, these three people are very likely to be members of Chen Taizhou's organization.The police here also agreed.

trial room.Although this Tashui town is much dilapidated compared with the former Jinbu town, the interrogation room of the Public Security Bureau looks quite new.Maybe it's because of the high quality of local residents?Simple folk?Few people commit crimes?So the interrogation room is not often used.

The glasses man and the others were divided into three rooms.Yu Fan faced the man with glasses, while Chen Jiayang and Guo Na interrogated the other two alone.In fact, at the beginning, Yu Fan suggested that Chen Xingyang should interrogate the man with glasses, because after all, he is a professional policeman, and his interrogation skills should be richer, and the guy with glasses is the main member of the gang at first glance, so let Chen Xingyang interrogate , and the identity is also equal.

But Chen Xiangyang insisted on asking Yu Fan to interrogate the man with glasses.With the slogan of Tian Ji's horse racing, Chen Xingyang told Fan that he and Guo Na were both professional policemen, and interrogating the two young men would definitely yield something, but as for Yu Fan, he would be regarded as a second-class horse. He wasn't a policeman in the first place, but he was facing a professional liar, so even if he didn't ask anything, it wouldn't be a loss.

In fact, Yu Fan knew very well that this was an opportunity Chen Xiangyang gave Yu Fan. Among the three, only Yu Fan had the best psychological skills. For Trump, it is most appropriate to let Yu Fan deal with their core members.Moreover, Chen Xingyang also used the guise of Tian Ji's horse racing, in fact, it was to relieve Yu Fan's psychological pressure.

When Yu Fan entered the interrogation room, the man with glasses had been sitting there for a while, but before Yu Fan could speak, the man with glasses spoke first.

"Comrade, you are here."
