NCERT Class 7 Science - ACIDS, BASES and SALTS - Part 2 (Last Part)

Hi guys, today we are discussing the second and last part of the NCERT Class 7 Science chapter - Acids, Bases and Salts. Here's a brief summary of the important concepts covered in this chapter:
Acids: Acids are substances that have a sour taste and can turn blue litmus paper red. They react with bases to form salts and water. Examples of common acids include vinegar, lemon juice, and hydrochloric acid.
Bases: Bases are substances that have a bitter taste and can turn red litmus paper blue. They react with acids to form salts and water. Examples of common bases include soap, baking soda, and ammonia.
pH Scale: The pH scale is a measure of the acidity or basicity of a solution. The scale ranges from 0 to 14, with 7 being neutral, values below 7 being acidic, and values above 7 being basic.
Indicators: Indicators are substances that change color in the presence of an acid or base. Some common indicators include litmus paper, phenolphthalein, and methyl orange.
Neutralization: Neutralization is the chemical reaction between an acid and a base to form a salt and water. The pH of the resulting solution is neutral, i.e., it is 7.
Salts: Salts are ionic compounds that are formed when an acid reacts with a base. They have a characteristic crystalline structure and can conduct electricity when dissolved in water.
Overall, the chapter provides a good introduction to the world of acids, bases, and salts, and their importance in our daily lives.
Happy learning, and Keep it Simple! :)
