(a) When dilute hydrochloric acid reacts with sodium carbonate then sodium chloride, carbon dioxide, and water are formed. N a 2 C O 3 + 2 H C l ⟶ 2 N a C l + H 2 O + C O 2 (b) When dilute hydrochloric acid reacts with sodium hydrogen carbonate, Carbon dioxide gas is liberated. We recognize the presence of carbon dioxide by passing it through lime water which turns milky or a white precipitate of calcium carbonate is formed. This confirms that the gas is carbon dioxide.

Table of Contents • • • • • • • Why should the solution of sodium bicarbonate be boiled during titration with HCl? As the titration progresses, the color of the bromocresol green will begin to lighten a bit. Boiling for about a minute will expel carbon dioxide gas from the solution and raise the pH sufficiently to cause the color to change back to blue. What happens when you add sodium carbonate to hydrochloric acid? Answer: When dilute hydrochloric acid reacts with sodium carbonate, then sodium chloride, carbon dioxide and water are formed. What is the action of hydrochloric acid on Na2CO3? Hydrochloric acid reacts with sodium carbonate to give sodium chloride with the release of CO2 gas. What happens when an acid is added to a carbonate solution? When acids react with carbonates, such as calcium carbonate (found in chalk, limestone and marble), a salt, water and carbon dioxide are made. The carbon dioxide causes bubbling during the reaction, which is observed as fizzing. This type of reaction can be used to test unknown solutions to see if they are acidic. What is the side effect of sodium bicarbonate? What Are Side Effects Associated with Using Sodium Bicarbonate? • Aggravated congestive heart failure (CHF) • Cerebral hemorrhage. • Swelling (edema) • High blood sodium levels. • Low blood calcium levels. • Low blood potassium levels. • Muscle spasms (associated with low calcium levels) • Metabolic alkalosis. How can you determine the acidity of sodium carbonate solution?...

All metal carbonates and hydrogen carbonates react with acids to form a corresponding salt, carbon dioxide and water. Metal carbonate + Acid → Salt + Carbon dioxide + Water Metal hydrogen carbonate + Acid → Salt + Carbon dioxide + Water For example, sodium carbonate reacts with dilute hydrochloric acid as follows: N a 2 ​ C O 3 ​ ( s ) + 2 H C l ( a q ) → 2 N a C l ( a q ) + H 2 ​ O + C O 2 ​ ( g ) Sodium hydrogen carbonate reacts with dilute hydrochloric acid as follows: N a H C O 3 ​ ( s ) + H C l ( a q ) → N a C l ( a q ) + H 2 ​ O ( l ) + C O 2 ​ ( g )

Gas Evolving Reactions A gas evolution reaction is a chemical process that produces a gas, such as oxygen or carbon dioxide. In the following examples, an acid reacts with a carbonate, producing salt, carbon dioxide, and water, respectively. For example, nitric acid reacts with sodium carbonate to form sodium nitrate, carbon dioxide, and water (Table \(\PageIndex\): Reaction of acids with carbonates. In this reaction setup, lime water is poured into one of the test tubes and sealed with a stopper. A small amount of hydrochloric acid is carefully poured into the remaining test tube. A small amount of sodium carbonate is added to the acid, and the tube is sealed with a rubber stopper. The two tubes are connected. As a result of the acid-carbonate reaction, carbon dioxide is produced and the lime water turns milky. The test tube on the right contains limewater (a solution of calcium hydroxide, \(Ca(OH)_2\)). On the left, a solution of hydrochloric acid has been added to a solution of sodium carbonate to generate \(CO_2(g)\). The test tubes are sealed with rubber stoppers and connected with a delivery tube. As the reaction proceeds, the limewater on the right turns from clear to milky; this is due to the \(CO_2(g)\) reacting with the aqueous calcium hydroxide to form calcium carbonate, which is only slightly soluble in water. The entire experiment is illustrated in the following video: Video \(\PageIndex\), and the acid, \(H^+\), is reduced to \(H_2(g)\). The oxidation of meta...
