Solution x turned blue litmus to red and Solution y turned red litmus to blue.
Which gas is released when we put magnesium pieces in solution x?

Explanation

Given solution 'x' turned blue litmus into red so, 'x' is an acid.
Given solution 'y' turned red litmus into blue so, 'y' is a base.
a) The reaction of an acid (x) with a base to give a salt and water.
b) When we put magnesium pieces in solution releases hydrogen gas.
c) When zinc pieces are put in solution 'y' there will takes place a chemical reaction.
d) Acids produce more `H^+` ions in the given solutions, 'x' produces more `H^+` ions because it is an acid
