Definitions of Equivalent Weight ( Acid-Base Context )
(3) H 2 SO 4 OH-= H 2 O HSO 4- Molecular weight of sulfuric acid (H 2 SO 4) = 98.07 g/mol. Theoretical Equivalent weight of sulfuric acid (H 2 SO 4) = 98.07g/equivalent of H . Reasoning . 98.07 g/mol H 2 SO 4 (1 mole H 2 SO 4 / 1 equivalent of H ) = 98.07g/equivalent of H . In this example the magnitude of the equivalent weight of sulfuric acid is the same as the molecular weight.

Among the impurities in lime mud Na 2 O has the highest concentration followed by MgO SO 3 P 2 O 5 SiO 2 Al 2 O 3 Fe 2 O 3 and K 2 O. Since sodium compounds contain a large portion of SO 3 (in the form of Na 2 SO 4 ) they are by far the largest and most troublesome impurities due to their low melting temperatures (Figure 2).
