In this laboratory it is possible to perform quality control on five food samples. To carry out these tests, the pH must be measured with indicator paper and a pH meter, and then compared with a table of allowed values. For the development of this practice, you will have bottles with buffer solutions of pH 10, pH 7 and pH 4, respectively, five samples to measure pH, litmus paper, three watch glasses and a pH meter.
