The God of Rebirth

Chapter 371 Color Change ([-]th Update)

Then he said to the customers in the store: "I'm sorry, because no one asked about it, and I didn't expect that I should have taken the initiative to send the test report to everyone."

While talking, Shao Min came over with a stack of documents and distributed them to everyone one by one.

It took less than 1 minute before and after, and there was no time to copy it on the spot. Obviously, what Gu Yunnian said was true. This test report was prepared long ago, and it was not an excuse. I believed Gu Yunnian's words a little.

Looking at the test report again, the color copy, they don't understand the various component measurements and results on it, what they can understand is the signed and stamped identification result on the last page.

"The ingredients of this identified product are pure natural plants, and do not contain any metals and hormones that are harmful to the human body."

There is also the last fresh seal, the word capital on the front of the organization, which is the most authoritative identification in their minds.

Seeing that everyone's expressions became more relaxed, Gu Yunnian continued: "This test report was sent to the most authoritative testing center in Beijing for appraisal before the products of Jinxun Pavilion were officially launched. If you are still not at ease, you can Go to the testing agency to test it yourself.”

Following Gu Yunnian's last words, everyone present basically dispelled their last doubts and believed Gu Yunnian's words.

Of course, it doesn't matter if you don't believe it, Jinxun Pavilion is not afraid of them to test it.

Gu Yunnian began to test his works.

"I took a look. The skin care products brought by Ms. Xiao basically have the same problem. Of course, more detailed testing requires more sophisticated instruments and longer time to identify the results. I am here and can only Give everyone a color reaction to prove that there are these three ingredients in it."

She pointed to the test tube rack placed in the center of the coffee table, "The first six columns, as you all have seen, are diluted with a small amount of samples I collected from the evidence that the police will submit for inspection."

Then point to the next two columns, "The next two columns are for comparison, one column I will add lead ion solution, mercury ion solution and hormone solution respectively, and the other column is full of solvents for diluting samples."

Gu Yunnian took out three brown vials from the box and held them up for everyone to have a look at.

They didn't understand the letters in the front, and none of them didn't understand the words lead, mercury, and hormones in the back.

After showing it to everyone, Gu Yunnian joined the seventh test tube respectively.

Then he took out three bottles of reagents, "This is a color developer for lead ions, mercury ions, and hormones. When it encounters the corresponding ions, it will change color."

Gu Yunnian first dropped the lead ion color developer into the first row of test tubes with a dropper, and there was no change in the first four test tubes.

They looked a little disappointed, but as Gu Yunnian dripped the chromogen into the fifth test tube, someone immediately exclaimed excitedly: "It's changed!"

In an instant, a touch of blue appeared in the test tube, like a flower slowly blooming.

Seeing everyone looking at her in unison, the exclaimed woman quickly covered her mouth and smiled embarrassedly, "I've never seen such a miraculous sight, it seems to be a witch's magic, obviously the two kinds of water are transparent, but why? When they touch together they become such a beautiful blue."

It was a bright blue, like the color of gemstones.

Gu Yunnian just smiled at her. Indeed, chemical reactions are amazing to those who don't understand, and many people fall in love with chemistry because of this.

She lowered her head and continued to add color reagents to the remaining three test tubes. Not surprisingly, the sixth and seventh test tubes all showed color changes.

　Do you feel that the chemical reaction is like a witch's magic, the kind that changes the legs of a mermaid?

　　Just read the text, don’t be misled!Jin Ye returned his chemistry to the teacher a long time ago, and vaguely remembered that the color reaction of lead and mercury was not beautiful, so he didn't want to look for information.Ask Gu Xiaonian to study a beautiful color developer. ^_^
