1.	The addition of solid sodium carbonate to pure water results in :(a) an increase in H+ ion concentration (b) an increase in pH (c) no change in pH (d) a decrease in OH- concentration
Answer» (B) an increase in pH \(Na_2CO_3+H_2O\longrightarrow 2NaOH+H_2O+CO_2\) on hydrolysis of \(Na_2CO_3\) gives \(NaOH\) solution, water and Carbon dioxide gas. We know that, \(NaOH\) is a strong base. it means the \(P^H\) of pure water increase. Option : (b) an increase in pH

The addition of solid sodium carbonate to pure water results in :(a) an increase in H+ ion concentration (b) an increase in pH (c) no change in pH (d) a decrease in OH- concentration

Answer»

(B) an increase in pH

\(Na_2CO_3+H_2O\longrightarrow 2NaOH+H_2O+CO_2\)

on hydrolysis of \(Na_2CO_3\) gives \(NaOH\) solution, water and Carbon dioxide gas.

We know that, \(NaOH\) is a strong base.

it means the \(P^H\) of pure water increase.

Option : (b) an increase in pH
