DISADVANTAGE OF GLASS ELECTRODE
Generally the glass membrane potential is pH dependent, say at pH greater than 10, membrane potential is significantly influenced by pH change. Moreover practically it is tedious to determine its single electrode potential accurately as it depends many factors such as electrolyte concentration, diffusivity, temperature, chemical nature of electrolyte. So unlike Ag/AgCl or Saturated calomel electrode or metal electrodes like Pt, its potential depends many factors.
ADVANTAGES OF GLASS ELECTRODE
Glass electrodes ware most commonly used where the chemical inertness is required or the potential has to be measured in a liquid-based systems. A metallic one might corrode and plastic is non conducting. As a matter of fact, glass is also non-conductive but there is a special class of conducting glass which is used in this. This glass is coated with a nano-level thick coating of indium tin oxide and is called ITO glass.

Answer:
Some of the advantages and disadvantages of glass electrode are:
Advantages:
- Glass Electrode is a light weight building material and therefore it helps in reducing the dead load.
- The external glass is treated in such a way so as to prevent the heat absorption as well as the resistance to UV light. This is helpful in making the building energy really efficient.
- It offers unobstructed views which helps in making the interiors of home look big and good.
Disadvantages:
- Excessive use of glass because of glass electrode might result in psychological as well as real security concerns.
- It is a costly material and definitely needs to be handled with care and help.
- It further requires regular cleaning and in extreme conditions, the external cleaning as well as maintenance can be really challenging.
Explanation:
What is a Glass Electrode?
A Glass electrode is a membrane electrode that contains a shiny glassy (non-crystalline) solid membrane as its recognition element. This material present in electrode is in a cool liquid state.
