I have a problem in understanding the equivalent concept used in stochiometry.This is what i know about it....
Equivalent concept is similar to mole concept that means 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 equivalents.Now if we take the balance reaction:
3BaCl2+Al2[So4]3--->3BaSo4 + 2AlCl3
p q 0 0 [Before reaction]
p-3q 0 3q 2q [After reaction]
Where p and q are moles.
Now if we solve the problem with any of the above two methods the RESULT IS THE SAME.CAN YOU EXPLAIN ME WHY?
WHY EQUIVALENT CONCEPT AND MOLE CONCEPT GIVE SAME RESULTS?
