MLIM HNO, solution 260 ml. De water 30 mL 0.1 M NaOH solution PROCEDURE The pH meter should already be calibrated at pH 4, 7 and 10. If your pH meter appears not to be operating properly, notify your TA and they will recalibrate the meter. Please handle the pH probe carefully the tip is made of a fragile glass membrane. Be sure to rinse the probe with water and blet...
