Solution

Solution Steps

Step 1: Understanding the Definition of an Acid

To determine the best definition for an acid, we need to consider the common characteristics of acids in chemistry. According to the Brønsted-Lowry theory, an acid is a substance that donates protons (H⁺ ions) in an aqueous solution.

Step 2: Analyzing the Options

Let's analyze each option:

a) Acids split into two molecules in aqueous solution: This is not a general definition of acids. While some acids may dissociate into ions, this statement is not specific to acids.
b) Acids remove a proton from each water molecule: This describes a base, which accepts protons, not an acid.
c) Acids donate protons in aqueous solution: This aligns with the Brønsted-Lowry definition of an acid.
d) Acids accept protons from water molecules: This describes a base, not an acid.
