Question

Every metal reacts with acids evolve h2o gas ?

Answer 1

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 created.
