Erlenmeyer flask‚ weighing balance‚ Graduating Cylinder‚ burette and pH meter were used in our experiment. In our first part of our experiment to prepare a primary standard‚ 0.1 M solution of KHP‚ we carefully weighed out 2.04g of KHP in a weigh paper using the weighing balance and transferred the measured KHP into a 100ml volumetric flask. We rinsed the weigh boat with distilled H2O to make sure that all the measured KHP is transferred into the flask and added distilled H2O into the flask until
