Calculate the molarity of each ion present in each of the following solutions. 0.25 M AlCl3 0.375 M Na2CrO4

Question

Calculate the molarity of each ion present in each of the following solutions.

0.25 M AlCl3

0.375 M Na2CrO4

Answer 1

AlCl₃ ------ Al³⁺ + 3 Cl^-

0.25 0.25 3*0.25= 0.75

Na₂CrO₄------ 2 Na⁺ + CrO₄^2-

0.375 2* 0.375= 0.75 0.375
