Their types of solvents such as protogenic solvents, amphiprotic solvents, etc. They create solvated protons when they react with acids. Therefore, when an acid HA undergoes dissociation it gives rise to a proton and the. Non-aqueous titrations are the titrations in which weakly acidic or basic substances are estimated using non-aqueous solvents to get a sharp end point.

Basic drugs such as Ephedrine, Morphine, Adrenaline, Caffeine, etc. These are mainly used to dilute the reaction medium and dissolve the water-insoluble drugs.
