Salts

Salts are chemical compounds that are formed from the reaction between an acid and a base. They are composed of positively charged ions, known as cations, and negatively charged ions, known as anions. Salts have a wide range of uses, including in cooking, industry, and agriculture.

Formation of Salts

When an acid reacts with a base, a neutralization reaction occurs, resulting in the formation of a salt and water. For example, when hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH), the salt sodium chloride (NaCl) is formed along with water (H2O).

Properties of Salts

Salts are typically solid, crystalline substances at room temperature. They have high melting and boiling points and can conduct electricity when dissolved in water or melted. The properties of salts vary depending on the specific cations and anions that make up the compound.

Common Salts

There are many different types of salts, each with its own unique properties and uses. Some common salts include sodium chloride (table salt), potassium nitrate (saltpeter), calcium carbonate (chalk), and magnesium sulfate (Epsom salt).
