Two solutions are mixed together; A solutions containing 0.0032 moles of HNO3 and a solutions containing 0.00421 moles of NaOH. How much NaoH will remain after the reaction?
Because the potential of pH electrodes can vary, it is necessary to CALIBRATE a pH electrode before use. For many uses, a two-point calibration procedure is appropriate.
