WebHow to calculate the molarity of either the H + or OH – when given the pH of a solution: Step 1: Using the formula for pH (pH = -log [H + ]), plug in your value for pH. Divide both sides of the equation by the negative sign. -pH = log [H +] Step 2: Using your scientific calculator, calculate the value for pH. WebCalculate the pH of a solution prepared by adding 55.0 mL of a 0.120 M NaOH solution to 100.0 mL of a 0.0510 M solution of oxalic acid ( HO2CCO2 H), a diprotic acid (abbreviated as H2ox). Oxalic acid, the simplest dicarboxylic acid, is found in rhubarb and many other plants.
WebWe also need to calculate the percent ionization. So the equation 4% ionization is equal to the equilibrium concentration of hydronium ions, divided by the initial concentration of the acid, times 100%. The equilibrium concentration of hydronium ions is equal to 1.9 times 10 to negative third Molar. So we plug that in.
