Question

What happens when acids react with metal??​

Answer 1

When an acid reacts with metal, a salt and hydrogen gas are produced:

acid + metal → salt + hydrogen.

An example:

nitric acid + calcium → calcium nitrate + hydrogen

The salt that is produced depends upon which acid and which metal react.

Answer 2

ANSWER

_______________

• Acid is a very dangerous liquid because it is corrosive and it can 'eat away' almost anything. However when it reacts with some objects it produces some gas.

• When acids react with metals, they produce a salt and hydrogen gas. Most metals react with acids, but not all. The general equation that describes the chemical reaction between an acid and metal is metal + acid = salt + hydrogen gas.

Example: Iron + hydrochloric acid =iron chloride and hydrogen gas (Fe + 2CHI = FeCI2 + H2)

• To write a general word equation for the reaction of metals and acids you to present it like this :

• metal + acid = salt (metal + acid i.e magnesium sulphate) + Hydrogen

• If you put a lit splint in the gas produced when a metal reacts with an acid it burns with a squeaky pop, due to the hydrogen
