Question

Write a balanced chemical equation for the standard formation reaction of solid sodium hydrogen carbonate nahco3 .

Answer 1

The balanced chemical equation for the standard formation reaction of solid sodium hydrogen carbonate (NaHCO3) is: 2 NaHCO3(s) -> Na2CO3(s) + CO2(g) + H2O(l). This equation shows that when solid sodium hydrogen carbonate is heated, it decomposes into solid sodium carbonate, carbon dioxide gas, and water.

Step-by-step explanation:

The balanced chemical equation for the standard formation reaction of solid sodium hydrogen carbonate (NaHCO3) is:

2 NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(l)

This equation shows that when solid sodium hydrogen carbonate is heated, it decomposes into solid sodium carbonate, carbon dioxide gas, and water. This reaction is known as a decomposition reaction.

Answer 2

There are a number of methods of which we can form sodium bicarbonate. This compound is commonly known as baking soda. It can be prepared from the reaction of sodium hydroxide and carbonic acid. Carbonic acid in water dissociates into hydrogen ions and the bicarbonate ion while sodium hydroxide would ionize into sodium ions and hydroxide ions. With this, these ions would react and form the sodium bicarbonate salt and water. The chemical reaction would be expressed as follows:

NaOH + H2CO3 = H2O + NaHCO3

Sodium bicarbonate is used in cooking, as a toothpaste and as a cleaning substance. Also, it is used in medical applications like for the preparation of the dialysate solution.
