Question

Basicity of organic acids can be determined by​

Answer 1

Answer:

pH paper....if it's more than seven then it's surely basic

Answer 2

Basicity of organic acid can be determined from the number of replaceable hydrogen ions or protons (H⁺) in one single acid molecule.

• Organic acids are weakly acidic organic compounds ( those compounds with carbon and hydrogen atoms).
• For example, acetic acid (CH₃COOH) is an organic acid with carbon and hydrogen whereas sulphuric acid (H₂SO₄) donot have carbon atoms and is an inorganic acid.

Determining the basicity:

• If an organic acid can loose one hydrogen ion, it is mono basic.
• If it can loose two hydrogen ions, it is dibasic.
• If it can loose three hydrogen ions it is tribasic.
• To determine the basicity of acetic acid in present example, the number of replaceable hydrogen ions is to be traced.
• Acetic acid looses one hydrogen ion to form acetate ion (CH₃COO⁻) so its basicity is one. Acetic acid is monobasic.

Therefore, the basicity of organic acids can be determined from the number of replaceable hydrogen ions.
