Question

Calculate the concentrations of the ion(s) indicated in each of the following solutions.

[Al^+3] and [SO4^-2] in 0.080 M Al2(SO4)3

Answer 1

Al₂(SO₄)₃ ==> 2Al³⁺(aq) + 3SO₄^2-(aq)

If you begin with 0.080 M Al₂(SO₄)₃ you will end up with

0.08 x 2 Al³⁺ = 0.16 M Al³⁺

0.08 x 3SO₄^2- = 0.24 M SO₄^2-
