Question

Moisture should be avoided in non aqueous titration
to........of the end point​

Answer 1

Answer:

The need for non-aqueous titration arises because water can behave as a weak base and a weak acid as well, and can hence compete in proton acceptance or proton donation with other weak acids and bases dissolved in it.

Answer 2

Moisture should be avoided in non-aqueous titration to neutralize the solution to reach the endpoint.

Explanation:

• The requirement for non-aqueous titration has arisen because water can behave as a weak base and a weak acid as well, and can hence proton acceptance of proton donation with other weak acids and bases can be done and dissolved in it.
• samples are fats or oils. components of mixtures of acids or bases have to be determined separately by titration.
• The indicator  which is used for non-aqueous titration includes
• Crystal Violet-It is the most common indicator in non-aqueous titration is Crystal violet.
• It is used in glacial acetic acid as 0.5 % w/v solution.
• Methyl Red-It is made in dioxin in a 0.2% w/v solution. The Color changes in the endpoint from yellow to red.
