Question

Molarity of 0.6 N aluminium sulphate is

Answer 1

The molarity of aluminum sulfate solution is 0.1 M

Explanation:

We are given that:

• Normality of aluminum sulfate  = 0.6 N

Solution:

• The formula of normality is

N = n x M

n - factor is the charge on Cation/anion.

Charge on Al ion = 2(+3) = +6

Here the value of n - factor = 6

Now put the values in the formula

N = n x M

 0.6 = 6 × Molarity

Molarity = 0.6 / 6 = 0.1 M

Thus the molarity of aluminum sulfate solution is 0.1 M
