Question

Is the pH greater than, equal to, or less than 7 after the neutralization of each of the following pairs of acids and bases? -NH3 and HClO4 -NaOH and benzoic acid -KOH and HBr -(CH3)3N and HOBr

Answer 1

A strong electrolyte dissociates completely into its ions but in weak electrolyte only certain number of ions are dissociated so pH depends upon the dissociated ions.

Definition of pH

An evaluation of how basic a substance or solution is its pH is determined. pH is measured on a scale from 0 to 14. A pH value of 7 is considered to be neutral on this scale, which implies it is neither acidic nor basic. If the pH value is less than 7, it is considered to be acidic and if the pH value is greater than 7, it is considered to be basic.

pH < 7 for NH₃ and HClO₄ since the acid is strong acid and the base is weak base.

The pH value for NaOH and Benzoic acid is pH > 7, since the base is strong base and acid is a weak acid .

pH = 7 for HBr and KOH since both are strong acid and strong base

pH < 7 or pH > 7 since both are neutral.
