Question

В лаборатории имеются оксид углерода (IV) и водные растворы хлорида цинка, едкого кали и нитрата серебра. Напишите уравнения химических реакций, которые могут протекать между этими веществами

Answer 1

CO2,ZnCl2,KOH,AgNO3

1)CO2+ZnCl2≠реакция не идёт,т.к. оксиды не реагируют с солями

2)CO2+2KOH=K2CO3+H2O

3)CO2+AgNO3≠реакция не идёт,т.к. оксиды не реагируют с солями

4)ZnCl2+2KOH=Zn(OH)2+2KCl
*(если щёлочь в избытке,то реакция протекает дальше)
*Zn(OH)2+2KOH+KCl=K2[Zn(OH)4]+KCl

5)ZnCl2+2AgNO3=Zn(NO3)2+2AgCl(бело-творожистый осадок)

6)KOH+AgNO3=KNO3+AgOH (но AgOH разлагается)
2AgOH+KNO3=Ag2O+H2O+KNO3

Answer 2

Chemical Reactions in the Laboratory

In the laboratory, there are carbon dioxide (IV) oxide and aqueous solutions of zinc chloride, caustic potash, and silver nitrate. Let's explore the chemical reactions that can occur between these substances.

1. Reaction between Carbon Dioxide (IV) Oxide and Zinc Chloride: The reaction between carbon dioxide (IV) oxide and zinc chloride can be represented by the following chemical equation: ``` CO2 + ZnCl2 → ZnCO3 + Cl2 ``` Source: 2. Reaction between Carbon Dioxide (IV) Oxide and Caustic Potash: The reaction between carbon dioxide (IV) oxide and caustic potash can be represented by the following chemical equation: ``` CO2 + 2KOH → K2CO3 + H2O ``` Source: 3. Reaction between Carbon Dioxide (IV) Oxide and Silver Nitrate: The reaction between carbon dioxide (IV) oxide and silver nitrate can be represented by the following chemical equation: ``` 2AgNO3 + CO2 → Ag2CO3 + 2NO2 + O2 ``` Source: These are the chemical reactions that can potentially occur between the given substances in the laboratory.
