Answer ) Na2CO3 NaCl and NaNO3 are salts of strong acids and strong bases.So they are neutral salts.In the case of NaHCO3 and Na2CO3 , in aqueous solution of Na2CO3 it does not donate H+ ion to water whereas NaHCO3 donates H+ ion to water.So NaHCO3 is more acidic and has low pH. Hence Na2CO3 has highest pH(most basic)
