ChemistryHydrogenJEE Main
Options:
  • A $\mathrm{H}^{-}(a q)+\mathrm{H}_2 \mathrm{O} \rightarrow \mathrm{H}_3 \mathrm{O}^{-}(a q)$
  • B $\mathrm{H}^{-}(a q)+\mathrm{H}_2 \mathrm{O}(l) \rightarrow \mathrm{OH}^{-}(a q)+\mathrm{H}_2(g)$
  • C $\mathrm{H}^{-}(\mathrm{aq})+\mathrm{H}_2 \mathrm{O}(l) \rightarrow$ No reaction
  • D None of these

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