Question

20 ml of 0.2 M Al2(SO4)3 aq. is mixed with 20
ml of 0.6 M BaCl, aq. solution. Calculate
concentration of A1+3 ion.
(1) 0.2 M
(2) 0.1 M
(3) 10.9 M
(4) 0.25 M​

Answer 1

Answer:

The answer is 1.- 0.2M

Explanation:

In the reaction above we have Al2(SO4)3 and BaCl. We are asked the concentration of Al+3 ion. As it can be observed that Al is only present in Al2(SO4)3 whose concentration is 0.2 M. Also in any compound Concentration of every ion is same. So the concentration of Al in Al2(SO4)3 will be same even in the mixture of two compounds.

Hence, answer is 0.2M
