उत्तर
basic, acidic, basic
Explanation:
\[\ce{\underset{Basic in nature}{HCOONa} + H - OH ⇌ \underset{strong base}{NaOH} + \underset{weak acid}{H - COOH}}\]
\[\ce{C6H5NH3Cl^- + H - OH ⇌ \underset{acidic}{H3O^+} + C6H5 - NH2 + Cl^-}\]
\[\ce{\underset{basic}{KCN} + H - OH ⇌ \underset{strong base}{KOH} + \underset{weak acid}{HCN}}\]
