Class 7 Science Chapter 5 Acids, Bases, and Salts: Important Topics

Acids have a sour taste, turn blue litmus red when mixed with water, and dissolve in water to release hydrogen ions.On the other hand bases have a bitter taste, and a soapy feel, turn red litmus blue, and produce hydroxide ions (OH–) in water.Salts are ionic substances that are formed when an acid and a base react to neutralize each other

Natural Indicators around Us

Natural indicators can be defined as a type of indicator that can be found naturally and that can determine whether the substance is an acidic substance or a basic substance. Some of the natural indicators around us are, an acid (e.g. vinegar, lemon juice), purple in an alkali (e.g. bicarbonate of soda, bleach), and green is something that is neutral (e.g. water). Many plants contain their own indicators – turmeric, red cabbage juice, and beetroot juice are three good examples. Other examples are tea and red grape juice.

Neutralization

Neutralization is a chemical reaction in which acid and a base react with each other, neutralize or nullify each other’s effect, and produce salt and water. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.

Neutralization in Everyday Life

In everyday life, neutralization is employed in different applications. For example, it is used in the neutralization of stomach acidity, neutralizing the soil, the prevention of tooth decay, the treatment of ant bites, etc.
