Question
In the laboratory preparation of Hydrogen, dilute nitric acid cannot be used because:
- Nitric acid is a strong oxidizing agent and can oxidize the hydrogen gas into water.
- Nitric acid is a reducing agent and reduces ZnCl2 into Zn.
- Nitric acid does not contain more hydrogen ions.
- All of these
Hint:
A weak reducing agent can't be used.
The correct answer is: Nitric acid is a strong oxidizing agent and can oxidize the hydrogen gas into water.
The correct option is a)Nitric acid is a strong oxidizing agent and can oxidize the hydrogen gas into water.
Nitric acid is a very strong oxidizing agent. It oxidizes the hydrogen gas produced when it reacts with metals to produce water. For this reason, nitric acid cannot be used to generate hydrogen gas.
