Question

How do metals react with an acid? Give a chemical equation. Name the gas evolved during the reaction.​

Answer 1

Answer:

Dilute acids react with relatively reactive metals such as magnesium, aluminium, zinc and iron. The products of the reaction are a salt plus hydrogen gas. Here's a good way to remember it: MASH (M+A→S+H).

Answer 2

Answer:

• When metals react with an acid it displaces hydrogen from its acid and make a salt with the rest of acid.

$\boxed{\sf Acid+Metal\longrightarrow Salt+H_2}$

Ex:-

$\boxed{\sf \bigstar{Mg\atop Magnessium}+{HCl\atop Hydrochloric Acid}\longrightarrow{MgCl_2\atop Magnessium\:Chloride}+{H_2\atop Hydrogen}}$

$\boxed{\sf \bigstar{Cu\atop Copper}+{H_2SO_4\atop Sulphuric\:Acid}\longrightarrow {CuSO_4\atop Copper\;Sulphate}+{H_2\atop Hydrogen}}$
