What is a water-soluble base called?
Answer and explanation
Correct answer: Alkali
A base is a substance that neutralises an acid, but bases differ in their solubility. A base that dissolves in water is specifically called an alkali; examples include sodium hydroxide and potassium hydroxide. Thus option B is correct. An acid has acidic properties, a salt is generally formed in a neutralisation reaction, and an indicator changes colour to show whether a solution is acidic or basic. These terms are not synonyms for alkali.
