Answer:
To make soluble salts using a metal or an alkali base, you typically start by reacting the metal or alkali base with an acid. This reaction is called neutralization. The metal or alkali base reacts with the acid to form a salt and water. The resulting salt is soluble in water, which means it dissolves easily. The process involves carefully mixing the metal or alkali base with the acid, ensuring that the reaction occurs completely. The resulting solution can then be filtered or evaporated to obtain the soluble salt.
