Glass electrodes are a type of ion-selective electrode used to measure the hydrogen ion activity in a solution, effectively determining its pH. The core of a glass electrode is a thin glass bulb made of a special type of glass, typically a silicate glass containing lithium, sodium, and calcium oxides. This glass is permeable to hydrogen ions.
When the glass bulb is immersed in a solution, a hydrated layer forms on its surface. Within
A reference electrode, such as a calomel electrode or a silver/silver chloride electrode, is also immersed in
