2. The _____ of a weak acid is strong.Im not sure I am thinking its a base but Im not sure.-1. Calculate the hydrogen ion concentration of an aqueous solution, given the concentration of hydroxide ions is 1 x 10^-5 M and the ion constant for water is 1 x 10^-14.......
1. Calculate the hydrogen ion concentration of an aqueous solution, given the concentration of hydroxide ions is 1 x 10^-5 M and the ion constant for water is
1 x 10^-14.

I am really confused! How would you do this?

2. The _____ of a weak acid is strong.

I'm not sure I am thinking it's a base but I'm not sure.

1. Calculate the hydrogen ion concentration of an aqueous solution, given the concentration of hydroxide ions is 1 x 10^-5 M and the ion constant for water is 1 x 10^-14.

You probably know that [H^+][OH^-] = Kw = 1.0 x 10^-14. So, algebra will help you solve this problem easily. You have only one unknown left, [H^+].

[H^+] = (1 x 10^-14)/(1 x 10^-5) = You can calculate this.

In an aqueous solution, a weak acid exists in equilibrium as follows:

Weak acid = HA

HA(aq) + H2O(l) <=> H3O^+(aq) + A^-(aq)

Note: H3O^+ is the conjugate acid. H3O^+ (or H^+) is the strongest acid that can exist in water.

Correct answer: The conjugate acid of a weak acid is strong.

Hope this is helpful to you. JIL HIR
