When using a pH meter to monitor a stirring reaction mixture, where should you place the pH sensor electrode? Select one: O Between the stirring vortex and the side of the glassware In the middle of the stirring vortex of the solution Along the edge of the glassware O Suspended above the reaction mixture



Answer :

While using a pH meter to monitor a stirring reaction mixture, the pH sensor electrode should be placed between the stirring vortex and the side of the glassware.

The pH meter is an electric device which is used to measure the hydrogen-ion activity in water-based solutions. This means that it is used to measure the pH of the solutions and determine which is the acidic or alkaline.

The pH meter is made up of a voltmeter which is attached to a pH-responsive electrode and a reference electrode.

The pH-responsive electrode is usually made of glass while the reference electrode is usually a silver–silver chloride electrode.

While monitoring the stirring reaction mixture, the pH-responsive electrode written above is usually placed between the stirring vortex and the side of the glassware.
