(a) Lime juice is acidic in nature. This is because it contains citric acid, which gives it a pH less than 7, the neutral point on the pH scale.

(b) Human blood is slightly alkaline, not acidic. It has a pH between 7.35 and 7.45, which is slightly above the neutral point.

(c) Lime water is also alkaline in nature. It is a solution of calcium hydroxide, which is a base.
