D. 2.2 - 10.2

Answer: Option A

Solution(By Examveda Team)

Glass electrode can be used for the estimation of soil pH range of 1.0 - 9.0.
A glass electrode is a type of ion-selective electrode made of a doped glass membrane that is sensitive to a specific ion. It is commonly used to measure pH.
Glass electrode with a glass membrane special, chemically pure, soft glass paired with a calomel reference electrode for estimation of soil pH.
