[H3O+] = 10-pH = 10-(14.0-pOH) = 10-(14-1.3) = 10-(12.7) = 2.0 x 10-13 mol/L
pH + pOH = 14 pOH = -log[0.1] = 1 pH = 13
pH + pOH = 14. So pOH = 14 - 1.12 = 12.88 pOH = -log[OH-] [OH-] = 1.31 x 10-13 M

0.1 molar means hydrogen ion concentration is 10^-1. so pH=-log[H+] ion. so pH =1. again we know that , pH+poh=14 so poh =14-1=13
1000 times more at pH = 10 (Calculation: 10-[pH2-pH1] = 10-(13-10) = 103 )
Since pH is a logarithmic scale, each increase (or decrease) by 1 means 10 times, so the change of pH in a solution from 10 to 11 would be 10 times, 11 to 12 would be 10 times, and 12 to 13 would be 10 times, and (10)(10)(10) is 1000, so a solution with pH 13 is 1000 times more basic then a solution with pH 10
