Question

В какой из реакций хлор не меняет свою степень окисления?А. 2 FeCl2 + Cl2 = 2 FeCl3 Б. KCl + F2 = 2 KF + Cl2 В. 2 KMnO4 + 16 HCl = 2 KCl + 2 MnCl2 + 5 Cl2 + 8 H2O Г. NaCl + HNO3 = NaNO3 + HCl

Answer 1

Правильный ответ под буквой Г, так как там реакция обмена.
А в первых случаях будет ОВР

Answer 2

Г это реация обмена

Answer 3

Reaction and Chlorine Oxidation State

In which of the reactions does chlorine not change its oxidation state?

The correct answer is: Б. KCl + F2 = 2KF + Cl2

In this reaction, chlorine does not change its oxidation state. It starts as -1 in KCl and ends as 0 in Cl2.

This information is based on chemical principles and the oxidation states of elements in compounds and reactions.
