Advantages and disadvantages of glass electrode

What is a glass electrode?

• The glass electrode is more generally used when chemical inertness is essential.
• The glass electrode is very sensitive.
• It is used for various types of applications.
• Easy and convenient to use for cleaning and calibration with standard buffer solution.
• It covers an acid range and an alkaline pH range.

• In general, the potential of the glass membrane depends on the pH.
• It is tedious to accurately determine the capacitance of your single electrode because it depends on many factors.
• Deposits on the electrode membrane can affect the pH measurement.
• Probability of breakage of fragile glass.
• The electrode is often needed to calibrate.
• Special types of buffer solutions are needed to calibrate them.

• A separate salt bridge is not necessary because it already contains a side tube with a solution of KCL (potassium chloride).
• The electrode potential is reproducible and consistent.
• They are comfortable, compact and relatively inexpensive.

• It can work as both anode and cathode half-cell.
• By creating a very small potential at the hydrogen electrode, its electrode potential can be considered zero.

• It's simple and inexpensive to prepare.
• Its results are stable and resistant.
• Covers a wide range of samples.
