Calculate the pH for each [H + ] given below: [H + ] = 0.00025; pH = 3.60 [H + ] = 1.0 x 10 -7 ; pH = 7.00 [H + ] = 2.3 x 10 -3 ; pH = 2.64 [H + ] = 7.6 x 10 -12 ; pH = 11.12 Determine the [H + ] from the pH: pH = 7.4; [H + ] = 3.98 x 10 -8 pH = 2.8; [H + ] = 0.00158 pH = 12.7; [H + ] = 2.0 x 10 -13 pH = 4.5; [H + ] = 0.0000316
