Question

7. Which of following gases is produced in the reaction of a metal with an acid?
a. Sulphur dioxide b. Carbon dioxide c. Oxygen d. Hydrogen​

Answer 1

Required Answer:-

Metals react with an acid to form the corresponding salt and hydrogen gas (D).

Some metals react violently, some less violently and some still remain inactive but most of the metals react with an acid.

• Sodium and Potassium are highly reactive with acids and react explosively with the evolution of H2 gas$.$
• Calcium and Magnesium also reacts but little less violently as compared to Na and K.
• Aluminium, Zinc and iron lesser than above.
• Copper, silver mostly remain inactive for dilute acids, but can react with strong acid.
• Nitric acid (HNO3) is an oxidising agent hence it oxidised H2 gas to form water.
• But Magnesium and Manganese react with nitric acid to give hydrogen gas.

Which of following gases is produced in the reaction of a metal with an acid?

a. Sulphur dioxide b. Carbon dioxide c. Oxygen d. Hydrogen​

$\huge \mathfrak {Answer}$

Option D

$\huge \mathfrak {Explanation}$

Hydrogen is produced when a reaction of a metal with acid.

Most metals react with acid.

The structure of solution is as follows :-

Firstly an acid solution is made from acid and water then some metal are thrown into the solution. Then the hydrogen bubbles form and we burn a matchstick and then a pop sound come
