Chapter 1063: Arsenic mirror experiment

Ye Tiandao, "All of you women are looking forward to marrying into a wealthy family. Look at this Hongying, even if you marry a prince, you will enjoy all the glory and wealth, but in the end, she will not die. What about the first beauty in the Qing Dynasty? What about special pets? It's not a tragic ending to a sudden death."
Zhuang Mengdie coughed and coughed, "Oh, yes, Ye Tian, ​​don’t do what you women do. Not all women want to marry a wealthy family. That's just the idea of ​​a small group of women. Most women still want to find one. It’s a dull and true love, and the two stay together for a long time. Besides, the experiment has not been done yet, so you can’t be so arbitrarily thinking that Hongying was poisoned to death, right?"
He Chuyao smiled and said, "Yeah, the experiment has not been done yet. Don't rush to conclusions. What if this Hongying died of illness instead of poisoning?"
Old Zhang said, "According to the analysis of historians, the possibility of death from illness is unlikely. It should have been poisoned. However, the medical level at that time could not detect the cause of death."
He Chuyao said, "In this case, let's go back and do the experiment. After you have said that, I can't wait to know the results of the experiment now."
Zhuang Mengdie said, "Let's go then, I also want to know how the first beauty of the Qing Dynasty died."
Ye Tiandao said, "Lao Zhang, let's go back and do the experiment first, and we will call you as soon as the results come out."
Lao Zhang nodded, "Okay, as soon as your results come out, it is estimated that it will immediately stir the entire historical world."
Ye Tiandao, "Is there such an exaggeration?"
Old Zhang said, "Of course, there are two factions about Hongying's death. Historians are divided into two factions. Some said that they died of illness and some were poisoned. The two factions have their own reasons and have been arguing. Of course, they still insist on poisoning. Most people died, and I myself firmly believe that Hongying died of poisoning."
Ye Tian nodded, "Well, let's go back and do the experiment, and we will definitely give you a satisfactory answer. Actually, I think I died of poisoning."
Ye Tian, ​​Zhuang Mengdie and He Chuyao hurried back to the police station.
As soon as the three of them entered the police station, they went straight to the material evidence department.
He Chuyao didn't even pant, so he hurriedly prepared the equipment for the experiment.
On the left is a test tube, in the middle is the alcohol furnace for experiment, above the alcohol furnace is a section of transparent glass tube, the glass tube is placed horizontally, the left end of the glass tube is connected to the test tube, and the right end is connected to a U-shaped bend.
Ye Tiandao, "What forensic doctor, why do you prepare so many experimental supplies?"
He Chuyao said, "Of course I did an arsenic mirror experiment. In fact, it is the arsenic mirror reaction. After a while, I will put zinc and concentrated hydrochloric acid in the test tube on the left, and then put my hair in the test tube, and put the alkali in the U-shaped tube. Lime and alcohol stoves are used to heat the gas in the test tube. After the hair is put into zinc and concentrated hydrochloric acid, if there is arsenic in the hair, the composition of the arsenic is , it will happen immediately The chemical reaction, the reaction equation is: As2O3+6Zn+12HCl=2AsH3+6ZnCl2+3H2O. AsH3 will accumulate in the glass tube when heated, forming a black and bright arsenic mirror. Oh, yes, the U-shaped tube also needs heating. Later, soda lime is unstable and will decompose immediately to produce gas."
Zhuang Mengdie said, "This experiment is still quite interesting, I will try it when I have time."
He Chuyao said, "Yes, this is actually a very simple chemical experiment. However, this method needs to pay attention to the heating temperature not exceeding 500 degrees, otherwise the hydrogen will explode. You can also fill it with carbon dioxide, nitrogen, hydrogen and other protective gases before heating. The temperature should not be too high to prevent arsenic gasification. It is recommended to use a elbow pipe to be immersed in a sand bath for heating, which can achieve better results."
Zhuang Mengdie said, "Oh? I see, the gas produced by the preheating decomposition of soda lime in that U-shaped bend is protective gas to prevent the temperature from becoming too high."
He Chuyao nodded, "Yes, so we must first heat the U-shaped elbow to decompose the soda lime in the elbow. When the soda lime decomposes in a large amount and the generated gas fills the transparent glass tube in the middle, then we must heat the A glass tube."
Ye Tiandao, "Huh? It's so lively, let's try it quickly. I can't wait to know the result."
He Chuyao said, "Don't worry, let the same thing happen slowly, you can't worry about doing experiments. Okay, we can heat the U-shaped tube now. Let the gas fill that section of the glass tube to form a protective gas. However, We don’t have a sand bath heating device here, so we have to use another alcohol stove."
After He Chuyao finished speaking, he placed another alcohol stove under the U-shaped bend.
"Now we are putting the deceased's hair in a test tube containing zinc and concentrated hydrochloric acid. Pay attention to this experiment. We must use high-concentration hydrochloric acid, otherwise the effect will not be obvious."
Hair enters the solution in the test tube, and the solution immediately starts to bubble,
He Chuyao said, "Did you see it, the reaction has already started, we can now turn on the alcohol stove under the transparent glass tube in the middle to heat it." After speaking, he immediately lit the alcohol stove.
After a while, a layer of black and shiny things gathered on the transparent glass tube.
Seeing this, He Chuyao immediately said excitedly, "Seeing that, the black and shiny thing is elemental arsenic. We succeeded. It seems that Hongying was indeed poisoned and died. We detected arsenic in her hair."
Ye Tiandao, "Oh? The result is out, then I will call Lao Zhang now to make him happy." After finishing speaking, he immediately dialed Lao Zhang's cell phone, but was told that the user was not in the service area.
Zhuang Mengdie laughed loudly, "Ye Tian, ​​you forgot, in the ghost place of Yinbao Building, the mobile phone has no signal."
Ye Tiandao, "I was so excited that I forgot. To reassure Lao Zhang, I simply call the Cyan Film Studio office and ask them to tell Lao Zhang." After speaking, he immediately dialed the number of the director's office.
The person who answered the call was Sister Wang. Sister Wang heard Ye Tian's voice and immediately asked, "Leader Ye, what's the matter?"
"Sister Wang, you send Xiao Manzi to tell Lao Zhang from the Cultural Relics Bureau that we have examined the hair of Hongying, but Hongying died of arsenic poisoning."
"Okay, no problem. I'll let him go."
Sister Wang put down the phone, and immediately ran to the staff dormitory, pulling Xiao Manzi who was playing the game, "Hurry up, stop playing, go to Yinbao Building and ask Lao Zhang to report a letter. Just say that. Hong Ying was poisoned to death."
Xiao Manzi sighed, "Okay, when I finish this one, I will go right away."
On the other side, Zhuang Mengdie sighed, "The relationship between Prince Rui and Hongying and Mochizuki Gege is really sad. If Hongying didn’t marry Prince Rui but married another man, would it be possible? It’s a good start and a good end."
