Sodium is a highly reactive alkali metal with atomic number 11. It’s silver-white, soft, and abundant in nature. It reacts vigorously with water, producing sodium hydroxide and hydrogen gas.
Identify the products formed when 1 mL of dil. Hydrochloric acid is added to 1g of Sodium metal.

When dilute hydrochloric acid (HCl) is added to sodium metal (Na), a chemical reaction takes place, resulting in the formation of sodium chloride (NaCl) and the liberation of hydrogen gas (H2).
The balanced chemical equation for the reaction is:
2Na+HCl →2NaCl+H2
So, for the reaction of 1 mL of dilute hydrochloric acid with 1 g of sodium metal, you can expect the formation of sodium chloride and the evolution of hydrogen gas. The balanced equation indicates that two moles of hydrochloric acid react with two moles of sodium to produce two moles of sodium chloride and one mole of hydrogen gas. If you’re working with a specific amount of sodium (1 g in this case), you can use the molar mass to determine the moles of sodium and then apply the stoichiometry of the balanced equation to find the expected amounts of sodium chloride and hydrogen gas formed.
