Question

Given the concentration of either hydrogen ion or hydroxide ion, use the ion product constant of water to calculate the concentration of the other ion at 298K

A. [H+]= 1.0*10^-4
B. [OH-]=1.3*10^-2

for A do you subtract 1.0*10^-14?
and for B do you divide 1.0*10^-14 and 1.3*10^-2

Answer 1

For A, no. (OH^-) = 1 x 10^-14/1 x 10^-4.
For B, (H^+) = 1 x 10^-14/1.3 x 10^-2.
