Question

26.
When solid B, was heated, a gas which formed a white precipitate when passed through
(Imk)
lime water was produce. The residue was dissolved in dilute nitric (V) acid to form a precipitat-
which dissolved on warming was formed.
Write the formula of the:
1. Cation in solid B1
(Imk)
II. Anion in solid B,
(1mk)
b) Write an ionic equation for the reaction between the residue and dilut
acid​

Answer 1

dissolves in water to give B. When excess

of CO2 is passed into B and gently

Explanation:

The compound A on heating gives a

colourless gas, and a residue which

dissolves in water to give B. When excess

of CO2 is passed into B and gently heated,

A is formed. The compound A is​
