Question

How can we test acetic acid if there is no availability of indicators

Answer 1

Explanation:

common acid-base indicator is phenolphthalein. Phenolphthalein is colorless in acidic solution, but changes to pink when the solution becomes basic. At the equivalence point, the moles of acetic acid are equal to the moles of sodium hydroxide, and the solution will turn pink as more sodium hydroxide is added.

Answer 2

Acetic acid

Explanation:

• A common acid-base indicator is phenolphthalein.
• Phenolphthalein is colorless in acidic solution, but changes to pink when the solution becomes basic.
• At the equivalence point, the moles of acetic acid are equal to the moles of sodium hydroxide, and the solution will turn pink as more sodium hydroxide is added.

Effect of litmus:

• Take a small amount of acetic acid in a test tube and dip a strip of blue litmus paper in it.
• Blue litmus turns red, It is acidic in nature.

Reaction with sodium bicarbonate:

• Take a small quantity of sodium bicarbonate solution in a boiling tube.
• The three most common indicators to test for acids and bases are: Litmus, Methyl orange, Phenolphthalein.
