Explain the action of dil.HCL on the following with chemical equations...
Action of Dil.HCL on Magnesium ribbon, Sodium hydroxide, and Crushed egg shells
1. Magnesium ribbon
Dilute hydrochloric acid reacts vigorously with magnesium ribbon to produce magnesium chloride and hydrogen gas. The chemical equation for the reaction is:
Mg + 2HCl → MgCl2 + H2
The magnesium ribbon dissolves in the acid because it is a reactive metal. The hydrogen gas is produced because magnesium displaces hydrogen from the acid.
2. Sodium hydroxide
Dilute hydrochloric acid and sodium hydroxide react to form sodium chloride and water. The chemical equation for the reaction is:
HCl + NaOH → NaCl + H2O
This reaction is a neutralization reaction. The acid and base cancel each other out to form a neutral salt and water.
3. Crushed egg shells
Eggshells are made up of calcium carbonate. Dilute hydrochloric acid reacts with calcium carbonate to produce calcium chloride, carbon dioxide, and water. The chemical equation for the reaction is:
CaCO3 + 2HCl → CaCl2 + CO2 + H2O
The reaction between the acid and the calcium carbonate produces carbon dioxide gas, which is visible as bubbles. The calcium chloride and water are formed as the products of the reaction.
