What is the H+ ion concentration of this solution?
A solution is made by dissolving 0.0112 g KOH in enough water to make 1.0 liter of solution. What is the H+ ion concentration of this solution?
a. ) 2.0 x 103 M
b. ) 8.0 x 102 M
c. ) 1.2 x 1013 M
d. ) 5.0 x 1011 M
e. ) 5.0 x 1012 M

Convert g KOH to mols KOH.
M = mols/L of solution.
(OH^) same as (KOH)
(H^+)(OH^) = Kw = 1 x 10^14
You know (OH^) and Kw; solve for (H^+). The answer is about 10^11 if I didn't make a mistake but you will need to work it out to get the exact answer.
