Question

What are the chemical products for magnesium \[ + \] dilute hydrochloric acid?

Answer 1

Hint: Metals are the chemical elements that are placed at the extreme left side of the periodic table in the first two groups namely alkali and alkaline earth metals. Magnesium belongs to alkaline earth metals that react with dilute hydrochloric acid to form magnesium chloride and hydrogen gas.

Complete answer:
Periodic table consists of different elements arranged in the increasing order of atomic numbers in vertical columns and horizontal rows. The vertical columns were known as groups and the horizontal rows were known as periods. There are a total of \[118\] elements arranged in \[7\] periods and \[18\] groups. The second group was named as alkaline earth metals
Magnesium is an element with atomic number \[12\] belonging to \[{2^{nd}}\] period and \[{2^{nd}}\] group. Magnesium has two electrons in its outer orbital. Thus, the valence electrons of magnesium are two.
Dilute hydrochloric acid is a strong acid which is diluted. Magnesium reacts with dilute hydrochloric acid to form an ionic salt known as magnesium chloride along with the liberation of hydrogen gas.
The chemical reaction for magnesium \[ + \] dilute hydrochloric acid is as follows:
\[Mg + 2HCl \to MgC{l_2} + {H_2}\]
Thus, the products formed on reacting magnesium and dilute hydrochloric acid is magnesium chloride \[\left( {MgC{l_2}} \right)\] and hydrogen gas \[\left( {{H_2}} \right)\]

Note:
The presence of hydrogen gas in the above chemical reaction can be identified by putting a gas splinter at the mouth of the test tube and making a heavy pop sound. The pop sound will be obtained when there is a presence of hydrogen gas only.
