• # question_answer The hydride ion ${{H}^{-}}$ is a stronger base than its hydroxide ion $O{{H}^{-}}$. Which of the following reactions will occur if sodium hydride (NaH) is dissolved in water [CBSE PMT 1997] A) ${{H}^{-}}(aq)+{{H}_{2}}O\to {{H}_{3}}{{O}^{-}}(aq)$ B) ${{H}^{-}}(aq)+{{H}_{2}}O(l)\to O{{H}^{-}}(aq)+{{H}_{2}}(g)$ C) ${{H}^{-}}(aq)+{{H}_{2}}O(l)\to \text{No reaction}$ D) None of these

$\underset{\text{base 1}}{\mathop{{{H}^{-}}(aq)}}\,+\underset{\text{acid 2}}{\mathop{{{H}_{2}}O(l)}}\,\to \underset{\text{base 2}}{\mathop{O{{H}^{-}}(aq)}}\,+\underset{\text{acid 1}}{\mathop{{{H}_{2}}(g)}}\,$
