What are acids and bases?

Acids are sour substances, while bases are not.

How do indicators work?

Indicators help differentiate between acids and bases.

Acid rain can harm the environment and historical monuments.

Acid and base reactions lead to neutralization and heat generation.

Balancing acidity and basicity is crucial for quality in various industries.

Acids like citric acid in lemon juice and artificial acids such as hydrochloric acid are responsible for the sour taste, while bases like magnesium hydroxide and calcium hydroxide are used in soap and detergent production.
Different indicators like litmus, turmeric, and China Rose can help distinguish between acids and bases based on color changes, with the neutralization of acids and bases resulting in a neutral substance, crucial for various applications from digestion to environmental protection.

Litmus is a natural indicator used to determine acidity or alkalinity.
Litmus solution is available in small paper tips in red and blue colors.
Red litmus paper turns blue in the presence of a base, while blue litmus paper remains unchanged.
Turmeric can be used as an indicator by making a paste with water and drying it on paper.
Turmeric paper remains yellow in the presence of an acid and turns red in the presence of a base.
Rubbing turmeric with soap, a base, changes its color to red due to its basic nature.
Another indicator can be created by breaking China Rose and leaving it to dry for a few hours, resulting in a light pink color.
The light pink indicator turns dark pink in the presence of an acid and dark green in the presence of a base.
Mixing an acid and a base neutralizes their effects, resulting in a neutral substance.
Acid rain, caused by pollutants like sulfur dioxide and nitrogen dioxide, can harm the environment, including historical monuments like the Taj Mahal.
