All the following will liberate a gas when reacted with dilute hydrochloric acid except
- A) sodium tetraoxosulphate (VI) salt
- B) Sodium trioxocarbonate (IV) salt
- C) Sodium sulphide
- D) Sodium trioxonitrate (V)
Correct Answer: A) sodium tetraoxosulphate (VI) salt
Explanation
This Chemistry question is asking which of the given options will not produce gas when reacted with dilute hydrochloric acid. The options are sodium tetraoxosulphate (VI) salt, sodium trioxocarbonate (IV) salt, sodium sulphide, and sodium trioxonitrate (V).When an acid reacts with a substance that contains a metal, it can produce hydrogen gas. In this case, we are looking for the option that will not produce gas when reacted with dilute hydrochloric acid.
The correct answer is option A, which is sodium tetraoxosulphate (VI) salt. This is because sodium tetraoxosulphate (VI) salt does not contain a metal that can react with the acid to produce hydrogen gas.
On the other hand, the other options contain metals that can react with the acid to produce hydrogen gas. For example, when dilute hydrochloric acid is added to sodium trioxocarbonate (IV) salt, it produces carbon dioxide gas.
It is important to understand the reactivity of metals with acids, as it is a key concept in Chemistry. For more information, please see the recommended textbooks.
