Question #31475

r coloured metal (A) is added to dilute sulphuric acid, solution (B) is formed which is colourless solution and a gas (c) is evolved which is colourless name ‘A’, ‘B’ and ‘C’ and write the equation?

Expert's answer

There are three colored metals - gold, copper and caesium. Only caesium reacts with diluted sulfuric acid, according to following equation:

2Cs + H_{2}SO_{4} = Cs_{2}SO_{4} + H_{2}

The solution of Caesium Sulfate is formed.

Hence,

A is Caesium (Cs)

B is solution of Caesium Sulfate (Cs_{2}SO_{4})

C is Hydrogen (H_{2})

2Cs + H

The solution of Caesium Sulfate is formed.

Hence,

A is Caesium (Cs)

B is solution of Caesium Sulfate (Cs

C is Hydrogen (H
