Statement 1 : The crystal structures of ${\mathrm{NaHCO}}_3\mathrm{and}{\mathrm{KHCO}}_3$ both show intermolecular hydrogen bonding but are different.

Statement 2 : In ${\mathrm{NaHCO}}_3\mathrm{and}{\mathrm{HCO}}_3^{-}$ ions are linked together through intermolecular hydrogen bonds into an infinite chain, while in ${\mathrm{KHCO}}_3,{\mathrm{HCO}}_3^{-}$ ions form dimeric anions through intermolecular hydrogen bonds.
