What Are Acids, Bases, and Salts?
Let’s delve into the basics. Acids, bases, and salts are three fundamental chemical categories that play pivotal roles in various chemical reactions and everyday processes. Understanding them is essential for grasping the underpinnings of chemistry and its impact on our world.
Acids
Acids are substances that donate hydrogen ions (H+) when dissolved in water. They typically have a sour taste and can react with bases to form salts and water. Common examples include hydrochloric acid (HCl) found in our stomachs aiding digestion, citric acid in citrus fruits, and acetic acid in vinegar.
Bases
In contrast to acids, bases are substances that accept hydrogen ions (H+) when dissolved in water. They typically have a bitter taste and feel slippery to the touch. Sodium hydroxide (NaOH) used in soap making and ammonia (NH3) found in cleaning products are examples of bases.

Salts
Salts are ionic compounds formed by the neutralization reaction of an acid and a base. These compounds are typically crystalline solids that dissociate into ions when dissolved in water. Table salt (NaCl), a familiar household product, is an excellent example of a salt formed from the neutralization reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH).
The pH Scale: Quantifying Acidity and Basicity
The pH scale, ranging from 0 to 14, is a crucial tool for measuring the acidity or basicity of solutions. A pH value below 7 indicates an acidic solution, while a pH value above 7 indicates a basic (alkaline) solution. A neutral solution, like pure water, has a pH of 7.
Understanding Chemical Reactions Involving Acids, Bases, and Salts
The interaction between acids and bases, known as neutralization reaction, is a cornerstone of chemistry. When an acid reacts with a base, they neutralize each other, producing salt and water. For example, the reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) yields sodium chloride (NaCl), common table salt, and water (H2O). This reaction is represented by the following chemical equation:
HCl (aq) + NaOH (aq) → NaCl (aq) + H2O (l)
Acids, bases, and salts also participate in various other types of chemical reactions. Acid-base reactions are crucial in countless industrial processes, from manufacturing fertilizers and pharmaceuticals to producing detergents and dyes. These reactions also play vital roles in biological systems, impacting the pH balance in our bodies and the acidity of our soils.
