• 3.2 M HI solution:
HI → strong acid → completely dissociates in the solution
HI → H+ + I-
[HI] = [I-]
[I-] = 3.2 M
• solution made by dissolving 145 g of NaI in water to make 150 mL of solution.
NaI → soluble ionic compound → completely dissociates in the solution
NaI → Na+ + I-
In each of the following pairs, indicate which has the higher concentration of I- ion.
3.2 M HI solution or a solution made by dissolving 145 g of NaI in water to make 150 mL of solution.
