Diazonium salts serve as intermediates for introducing various substituents into the aromatic ring through nucleophilic substitution reactions. In these reactions, the diazonium salt reacts with nucleophiles (e.g., F⁻, Cl⁻, Br⁻, I⁻, CN⁻, OH⁻, NO₂⁻), leading to the replacement of the diazo group. The nucleophile attacks the electrophilic carbon of the diazonium ion, resulting in the introduction of the desired substituent. The type of substituent introduced depends on the nature of the nucleophile used. These reactions provide a versatile and controlled method for functionalizing aromatic compounds, allowing for the synthesis of a wide range of organic derivatives.
Heating copper sulfate crystals causes them to undergo dehydration, leading to a change in color and composition.

Heating copper sulfate crystals causes them to undergo dehydration, leading to a change in color and composition. Initially, copper sulfate crystals are blue because of water molecules incorporated in their structure. Upon heating, these water molecules are driven off, leaving anhydrous copper sulfate. The color changes from blue to white as the anhydrous form lacks the water-associated color. The composition changes from CuSO₄·5H₂O (copper(II) sulfate pentahydrate) to CuSO₄ (anhydrous copper(II) sulfate). This dehydration is reversible; upon exposure to moisture, the anhydrous form can absorb water molecules, and the blue color is restored as it reverts to the pentahydrate.

Sodium hydrogen carbonate plays a crucial role in soda-acid fire extinguishers as the base component. In these extinguishers, a mixture of sodium hydrogen carbonate (baking soda) and a weak acid (typically tartaric acid) is stored separately. When the extinguisher is activated, a breaking mechanism releases the acid, initiating a chemical reaction. The acid reacts with sodium hydrogen carbonate, producing carbon dioxide gas. The rapid generation of carbon dioxide pressurizes the extinguisher and expels a solution of water, dissolved sodium carbonate, and the produced carbon dioxide. This effectively suppresses the fire by displacing oxygen and cooling the surrounding area.

Sodium hydrogen carbonate, or baking soda, functions as an antacid by neutralizing excess stomach acid. When ingested, it reacts with the acidic gastric contents, producing carbon dioxide, water, and salt. This reaction increases the pH of the stomach, providing relief from symptoms of indigestion, heartburn, or acid reflux. The carbon dioxide produced can also promote burping, helping to expel gas. While it offers temporary relief, excessive or frequent use is cautioned due to the sodium content, and individuals with certain medical conditions should consult healthcare professionals before using sodium hydrogen carbonate as an antacid.
