Which statement about bases is the most correct?
Answer and explanation
Correct answer: Bases can give hydroxide ions in water
The governing concept is the basic behaviour of substances in aqueous solution. A soluble base dissociates or reacts with water to increase hydroxide-ion concentration, giving OH⁻ ions in the solution. This is associated with turning red litmus blue. Option B reverses the litmus result, while C is too absolute because some bases are soluble and D describes an acid-like taste, not a property of bases. Therefore A is the most correct statement.
