Ans 4) CH3COOH
The compounds that are able to donate their proton to the other species are called as acids . Here CH3COOH or acetic acid , is an acid , as it donates its proton to a base and forms salt .
Rest all others are either bases or salts.

To calculate the concentration of a solution using acid–base titration data. In an acid–base titration, an acid (or base) of known concentration is added to a base (or acid) of unknown concentration until the number of moles of H+ and OH- are equal, a condition called the equivalence point. Since you know the number of moles of H+ (or OH- ) that you added, you can determine the number of moles of OH- (or H+) in the unknown solution. For...
