An equivalent is the number of moles of an ion in a solution, multiplied by the valence of that ion.
Number of mole of SO42- ion = 3
Valance(charge) of SO42- ion = 2
Equivalent of sulfate ion = 3 × 2 = 6
Ans = 6 Eq

I Review I Constants I Periodic Table When a chemical reaction occurs, atoms rearrange to form new compounds, but no new atoms are created nor are any destroyed. This concept is called conservation of Part A mass. Mass conservation can be seen in a balanced chemical equation, where the numbers of each kind of atom are the same on both sides of the reaction arrow. The figure (Figure 1) shows the reaction of...
