Concentration of ions in a solution?

Postby Antonio Melgoza 2K » Thu Nov 26, 2015 7:51 pm

I don't really understand one of the practice questions from 12.4 in the book. I attached a screenshot of the question. I'm not sure what the equation would be. Can anyone help?

HI is a strong acid so we can assume that there will be 100% dissociation. Therefore, a concentration of 6x10^-5 M HI would yield 6x10^-5 M of H+ (H30+). And then you can use the formula pH + pOH = 14 to get the concentration of OH-.
