WebCalculate [H3O+] using Ka equation (we can approximate “x” in denominator to be zero. You find your Ka value from a chart of Ka values): Ka = ([HCOO-][H3O+])/[HCO2H] Ka = (x 2)/(0.2-x) Ka = (x 2)/0.2. 1.77 x 10-4 = (x 2)/0.2. sqrt(1.77 x 10-4 x 0.2) = x. 5.95 x 10-3 = x. Since [H3O+] = x, [H3O+] = 5.95 x 10-3 M. Calculate pH: pH = -log[H3O ...
