FAQs on Acids, Bases and Salts Class 7 Notes CBSE Science Chapter 5 (Free PDF Download)
1. What is the Difference Between Acids and Bases?
As per the CBSE Class 7 Science Notes Chapter 5, acids are an aqueous solution of non-metallic oxides that are sour. Bases are metallic oxides that are bitter.
2. What is a Neutralization Reaction?
By referring to the Class 7 Chapter 5 Science notes, you will understand that a neutralization reaction is where an acid and a base react to make a salt and lose their individual chemical properties.
3. Why Should You Use Class 7th Science Chapter 5 Notes?
You can use these notes as revision material to study the chapter quickly before an exam.
4. State the differences between acids and bases as in Class 7 Science?
These two categories, that is, acids and bases are corrosive substances having acidic and basic properties. The differences between them would be as follows:
Acids are corrosive substances with a sour taste, whereas basic substances have a bitter taste.
An acidic corrosive substance turns a blue litmus paper to red, whereas a basic corrosive substance turns red litmus to blue.
Examples of acidic substances are curd, vinegar, etc. whereas basic substances would be soap, milk of magnesia, etc.
5. What are the concepts discussed in Chapter 5 of Class 7 Science?
In Chapter 5 of Class 7 Science, students learn about acids and bases in detail. They are made familiar with the acidic and basic nature of different substances with examples. The following are the various concepts discussed in the chapter:
Acids and bases, and their nature
Natural Indicators: Litmus and China Rose
Neutralization and its Examples in everyday life
These concepts can be better understood with revision notes because they are given in a simple structure.
6. What are the most important definitions in Chapter 5 of Class 7 Science?
Chapter 5 of Class 7 Science is all about 'Acids and Bases' and their various properties. The chapter is relatively easy to understand, with Revision notes designed in simple and short structures for Class 7 to understand. The following list contains some definitions from the chapter usually asked as questions for exams:
Acids, bases definitions
Acids and bases differences
Litmus paper
Phenolphthalein
Acidic and basic nature
Neutral Solutions
Neutralisation reaction
These are some of the topics which can be asked as definitions.
7. What is the neutralization reaction? Give an example, according to Chapter 5 of Class 7 Science.
In Chapter 5 Of Class 7 Science, students learn about the process of Neutralisation and its various examples in everyday lives. Therefore, neutralization can be defined as a reaction between an acid and a base resulting in a substance known as salt. The byproducts of this reaction are salt and water, and the formation of heat accompanies this process. Students can use the Revision Notes for Chapter 5 of Class 7 Science free of cost from the Vedantu website or from the Vedantu app, to better understand the concepts for exams.
8. What are some important equations from Chapter 5 of Class 7 Science?
The Chapter on 'Acids and Bases' are just introductions for Class 7 students and as such, do not deal with many equations. But there are some very important equations that students must learn and keep engraved in their memories. The equations are listed out below:
[Acid + Base = Salt + Water + H (stands for heat)]
[HCL + NaOH = NaCl + H2O]
[dil HCl + Ca(OH)2 = CaCl2 + H2O] (dil stands for dilute)
