A glass electrode is made of a doped glass membrane and is an electrode which is ion-selective.
The glass electrode is made in such a way that it is only sensitive to the specific ion.
A glass electrode is commonly used in a pH meter to measure the pH of a solution. The electrode contains a special glass membrane that responds to changes in hydrogen ion concentration in the solution.
The hydrogen electrode, specifically the standard hydrogen electrode (SHE), serves as a universal reference point for measuring electrode potentials in electrochemistry, providing consistency and comparability across experiments. Its advantages include simplicity in construction, reproducibility, and the ability to define the standard electrode potential as zero volts. Additionally, it facilitates the understanding of redox reactions and the behavior of other electrodes in relation to hydrogen, which is fundamental in various electrochemical applications.
It cannot be used above 50 degree because the Hg2Cl2 breaks down,yielding an unstable readings. Mercurous chloride used in calomel electrode is a toxic substance

Glass electrodes are highly accurate and have a fast response time, making them ideal for pH measurements. They are also durable and resistant to chemical corrosion, allowing them to be used with a wide range of solutions. Additionally, glass electrodes are easy to maintain and calibrate, making them a popular choice for pH measurement applications.
Standard electrode potential is a redox electrode. This is the forms the basis of the thermodynamic scale.
A pH electrode works by measuring the electrical potential difference between a reference electrode and a glass electrode. The glass electrode contains a special membrane that responds to changes in hydrogen ion concentration, which is used to determine the pH of a solution.
Potentiometric titration is a method to detect potential difference between the indicator electrode and reference electrode and thus determine concentration of chemical component, which reacts with reagent added to a solution potentially in equilibrium at the beginning.The popularly used reference electrode is either silver-silver chloride or mercury sulfate electrode, and the indicator electrode is generally made of glass electrode, platinum electrode and silver electrode or ion selective electrode.

A pH electrode works by measuring the electrical potential difference between a reference electrode and a glass electrode. The glass electrode is sensitive to hydrogen ions in the solution, which determines the acidity or alkalinity. The pH value is calculated based on this potential difference.
pH meters typically use glass electrodes to measure the pH of a solution. These electrodes are sensitive to changes in hydrogen ion concentration and provide accurate pH readings. Additionally, reference electrodes are used in combination with the glass electrode to ensure reliable and consistent measurements.

Using an electrode positive in welding processes can provide advantages such as better penetration, increased welding speed, and improved control over the welding arc.
A pH meter typically consists of a probe with a glass electrode, a reference electrode, and a meter that displays the pH value. The glass electrode measures the hydrogen ion concentration in a solution, while the reference electrode provides a stable reference point. The meter then calculates and displays the pH value based on the difference in electrical potential between the two electrodes.
