Final answer:
Bases do not react with salts to form acids; this is not a property of a base. Their actual properties include feeling slippery, tasting bitter, turning litmus blue, and neutralizing acids to form salt and water.
Step-by-step explanation:
The property that is NOT a characteristic of a base is that it "reacts with salts to form acids." In fact, bases have several notable properties: they feel slippery on the skin, taste bitter, turn litmus blue, and do not react with metals the way acids do.
Instead, when a base reacts with an acid, it typically produces a salt and water, a process known as neutralization.
