The correct answer is:
$\mathrm{H}^{-}(a q)+\mathrm{H}_2 \mathrm{O}(l) \rightarrow \mathrm{OH}^{-}(a q)+\mathrm{H}_2(g)$
$\underset{\text { base1 }}{\mathrm{H}^{-}(a q)}+\underset{\text { acid 2 }}{\mathrm{H}_2 \mathrm{O}(\mathrm{I})} \rightarrow \underset{\text { base2 }}{\mathrm{OH}^{-}(a q)}+\underset{\text { acid1 }}{\mathrm{H}_2(g)}$
