What happens when a base reacts with a metal?

Answer: The base has a harsh flavour and is slick to the touch. An alkali is a dissolved base in water. Salts are formed when such substances react chemically with acids. On red litmus paper, bases are known to become blue.

Hydrogen gas is formed when a base combines with a metal. When a burning candle is brought close to the test tube’s mouth, it makes a popping sound.
