WebStage 1. Using a small funnel, pour a few cubic centimetres of 0.4 M hydrochloric acid into the burette, with the tap open and a beaker under the open tap. Once the tip of the burette is full of solution, close the tap and add more solution up to the zero mark. (Do not reuse the acid in the beaker – this should be rinsed down the sink.) WebCalculation of pH is simple when there is a 1 × 10power problem. However, in real life that is rarely the situation. If the coefficient is not equal to 1, a calculator must be used to find the pH. For example, the pH of a solution with [H +] = 2.3 × 10 − 5M can be found as shown below. pH = − log[2.3 × 10 − 5] = 4.64.
