- (E) An acid salt contains one or more H atoms in the salt formula
separating a positive ion and the hydrogen-bearing negative ion. For
example, Na 2 SO 4 is a normal salt and NaHSO 4 is an acid salt because of the
presence of H in the hydrogen sulfate ion. In Ca(HCO 3 ) 2 , the same is true.
This is classified as an acid salt.
