At 25 °C, all of the following ionic compounds produce a basic aqueous solution, except ____.

A. NaF

B. Na3PO4

C. NaNO2

D. NaHSO4

Solutions

Expert Solution

A:- Except D. NaHSO4 remaining all compounds produce a basic aqueous solution, bacause NaHSO4 is dissolved in water to form strong acid and strong base,

Balanced equation,

NaHSO4 + H2O -------> NaOH + H2SO4

strong base strong acid

The remaining compounds, when dissolved in water to form strong base and weak acid, so a basic aqueous solution is produced by these compounds.

Balanced chemical equations,

NaF + H2O --------> HF + NaOH

weak acid strong base

Na3PO4 + 3 H2O --------> H3PO4 + 3 NaOH

weak acid strong base

NaNO2 + H2O -----------> HNO2 + NaOH

weak acid strong base
