This video shows you how to prepare pH 4 and pH 7 buffers for pH meter calibration using readily available low cost raw salts. These buffers have a strength of 0.1M. These are the amounts needed to prepare 250mL of buffer solution: • pH 4 • Potassium Citrate 2.63g • Citric acid monohydrate 3.45g • (if using anhydrous citric acid, use 3.15g) • pH 7 • Potassium Citrate 7.14g • Citric acid monohydrate 0.35g • (if using anhydrous citric acid, use 0.32g) • (Please notice that the Amazon links below are affiliate referral links.
