Question

the internal reference electrode in glass electrode is .​

Answer 1

Answer:

Glass electrode is a hydrogen-ion responsive electrode usually consisting of a bulb, or other suitable form, of special glass attached to a stem of high resistance glass complete with internal reference electrode and internal filling solution system. Glass electrode is also available for the measurement of sodium ions.

Answer 2

Answer:

The internal reference electrode in a glass electrode is usually silver chloride electrode or calomel electrode.

Explanation:

Glass electrode:

• An ion-selective electrode known as a glass electrode is one that is built of a doped glass membrane that is sensitive to a particular ion.
• Ion-selective glass electrodes are most frequently used for pH measurement.
• A glass electrode that is sensitive to hydrogen ions is the pH electrode.
• Glass electrodes are a crucial component of the equipment used in chemical analysis and physicochemical research.
• All chemical-sensing potentiometric electrodes have a metal electrode inside called the internal reference electrode.
• Additionally, specialized glass electrodes with ion sensitivity are employed to measure the concentration of ions such as lithium, sodium, ammonium, and others.
