How to calculate pH and pOH

Postby WUng_1D » Sun Nov 24, 2019 9:20 pm

For question 6B.5 it states...
Calculate the pH and pOH of each of the following aqueous solutions of a strong acid or base: (a) 0.0146 m HNO3(aq); (b) 0.11 mHCl(aq); (c) 0.0092 m Ba(OH)2(aq); (d) 2.00 mL of 0.175 m KOH(aq) after dilution to 0.500 L; (e) 13.6 mg of NaOH dissolved in 0.350 L of solution; (f) 75.0 mL of 3.5 3 1024 m HBr(aq) after dilution to 0.500 L

Not sure how to go about calculating the pH and pOH

find the concentration of hydrogen in the solution then take the negative log of the concentration

Then you can find the pOH by subtracting the pH you calculated from 14.
