Expert Answer
Equivalent concept is similar to mole concept i.e in any chemical reaction the reactants react in same equivalents to give same equivalents of products.
BaCl2+Al2[SO4]3 --->BaSO4 + AlCl3
a b 0 0 [Before reaction]
0 b-a a a [after rection]
Where a and b are the number of equivalents. ( Number of equivalents = weight/(equivalent weight) )
