Question

Briefly describe how you would determine whether a given salt will produce an acidic, basic, or

neutral solution when dissolved in water.

Answer 1

Answer:-

1) If the salt produces a strong acid and a strong acid when dissolved in water, the solution is neutal.

For e.g: KCl (salt) + H₂O   KOH (strong base) + HCl (strong acid)

Hence, the solution of KCl in water is neutral.

2) If the salt produces a weak acid and a strong base , the solution is basic in nature.

For e.g :- K​​​​​​​_{2​​​​​​​}CO₃ (salt) + 2 H​​​​​​​​​​​​​₂O   2 KOH (strong base) + H₂CO₃ (weak acid)

Hence, the solution of K₂CO₃ in water is basic.

3) If the salt produces a strong acid and a weak base , the solution is acidic in nature.

For e.g.:- NH​​​​​​​₄Cl (salt) + H₂O   NH₄OH (weak base) + HCl (strong acid)

Hence, the solution of NH₄Cl in water is acidic.
