a)Nahso4 because
formed by reaction of sodium hydroxide (NaOH) and acetic acid (Ch3cooh).
Acetic acid is a weak acid and sodium hydroxide is a strong base.
Thus , ( Nahso4) is basic in nature.
When Nahso4 added to Ch3cooh which is acidic in nature, the concentration of H+ decreases.
So , there is an increase in the pH of the solution
