How does sodium hydrogen carbonate neutralize acids in the blood?
Sodium hydrogen carbonate (baking soda) acts as a buffer in the blood by reacting with excess hydrogen ions from acids, forming water and carbon dioxide. This reaction helps to maintain the blood pH within a normal range by neutralizing the acidic substances.
The difference between ketones and carboxylic acids when reacting with sodium hydrogen carbonate?
Ketones do not react with sodium hydrogen carbonate, while carboxylic acids undergo a reaction with sodium hydrogen carbonate to produce salt, water, and carbon dioxide gas. This is due to the presence of the acidic -COOH group in carboxylic acids that can be neutralized by the bicarbonate ion in sodium hydrogen carbonate.
Is sodium carbonate soluble in hydrochloric acid?
Yes, sodium carbonate is soluble in hydrochloric acid. When sodium carbonate reacts with hydrochloric acid, it forms sodium chloride, carbon dioxide gas, and water.
What happens when hydrochloric acid is added to sodium hydrogen carbonate?
When hydrochloric acid is added to sodium hydrogen carbonate, a chemical reaction occurs. The acid reacts with the carbonate to form carbon dioxide gas, water, and sodium chloride. This reaction results in effervescence due to the release of carbon dioxide gas.
What are the reactants in sodium metals reacting with hydrochloric acid to produce salt and hydrogen gas?
The reactants are sodium metal (Na) and hydrochloric acid (HCl). The chemical reaction between them produces salt (NaCl) and hydrogen gas (H2).
