H2SO4, sulfuric acid. The gram-molecular mass is 98 (From the periodic chart the individual atomic masses are: H=1, S=32, O=16: {1x2}+32+{16x4}=98). The number of acid hydrogen ions (H+ ) is 2. Equivalent mass for H2SO4 is 98/2 = 49. H3PO4, phosphoric acid. The gram-molecular mass is also 98. The number of hydrogen ions (H+ ) is 3.

The solute-free ,mass fraction, of Na2SO4 in the solvent mixtures extended from 0 to 0.25. The solubility of Na2CO3 and NaHCO3 in Na2SO4–water solvent mixtures decreased with addition of Na2SO4. With rising temperature, the solubility of NaHCO3 increased while the solubility of Na2CO3 increased at first and then decreased after transition points.
