If a 0.1 mol/L solution is diluted to 0.01 mol/L, the:

Question

a) concentration of hydrogen ions increases
b) pH decreases
c) acidity constant decreases
d) the acidity constant does not change

I would think the ph decreases? no?

Answer 1

Let's see. If we dilute 0.1(pH = 1) to 0.01 (pH = 2), is that a decrease in pH? :-)
I think it can't be a, b, or c.
