Chemistry Question on coordination compounds
How many ions per molecule are produced in the solution when Mohr salt is dissolved in excess of water ?
A
4
B
5
C
6
D
10
Answer
5
Explanation
Solution
Double salt (such as Mohr salt) dissociate into simple substances or ions completely when dissolved in water. Mohr' salt is
FeSO4.(NH4)2SO4.6HzO
FeSO4.(NH4)2SO4.6HzO−>[Exces of ][water]Fe2++2NH4+2SO42−+6H2O
So, total ions dissociated 5.
