Question
Complete the following reaction and find ‘A’.
- CuCl2
- CuCl
Hint:
Metal oxides form chloride salts when reacting with hydrochloric acid.
The correct answer is: CuCl2
- Metal oxides react with acids to produce salt and water.
- The salt produced from these reactions is dependent on the acid that is used.
- Metal oxides form chloride salts when reacting with hydrochloric acid, nitrate salts when reacting with nitric acid and sulfate salts when reacting with sulfuric acid.
2HCl + CuO 
CuCl2 + H2O
A is CuCl2.
