NCERT Solutions for Class 10 Science Chapter 2: Points to Remember

Students can note down the important points to remember from NCERT Class 10 Science chapter 2 as mentioned below:

  • Indicator:
    (i) An indicator is a chemical substance which is used to indicate acidic or basic or neutral nature of an aqueous solution of a substance
    (ii) Indicators may be natural (litmus, turmeric and red cabbage,) or synthetic (phenolphthalein and methyl orange). Some indicators (onion paste, vanilla essence and clove oil) distinguish acids and bases with their odour. Such indicators are called olfactory indicators
  • Acids:
    (i) Acids are the substances that dissociate in water to give hydrogen ions (H+) or hydronium ions (H3O+)
    (ii) Acids may be classified as:
    (a) Organic and inorganic acids (On the basis of source from which they are obtained).
    (b) Strong and weak acids (On the basis of their extent of dissociation in aqueous solution).
    (c) Concentrated and dilute acids (On the basis of their concentration in water).
  • Acids taste sour and turn blue litmus to red. They are corrosive in nature. Their aqueous solutions conduct electricity.
  • Acids react with metals to form salt and hydrogen gas.
  • Acids react with metal carbonates and metal hydrogen carbonates to form salt, carbon dioxide and water.
  • Acids react with basic metallic oxides to form salt and water.
  • Bases:
    (i) Bases are the substances that dissociate in water to give hydroxide (OH–) ions. A base which is soluble in water is known as alkali.
    (ii) Bases are classified as strong and weak bases on the basis whether they dissociate completely in water or not.
    (iii) Bases are bitter to taste and turn red litmus to blue. They are soapy in touch and corrosive in nature. They conduct electricity in aqueous medium.
    (iv)Bases react with some active metals like zinc on heating to form salt and hydrogen gas.
    (v)Non-metallic oxides being acidic in nature react with bases to form salt and water.

FAQs on NCERT Solutions for Class 10 Science Chapter 2

Q.1: Which type of medicine is used for treating indigestion?
Ans: Antacid is used for the treatment of indigestion which is caused due to excess acidity in the stomach. Antacid being basic in nature, neutralises the acidity in the stomach.

Q.2: Why do acids not show acidic behaviour in the absence of water?
Ans: A substance is said to be acidic when it can generate Hydrogen Ion. Moreover, Hydrogen ions can only be produced in water. Thus, water must be present for acid to dissociate into a hydrogen ion and the respective anion. Hence, an acid fails to show its acidic behaviour in the absence of water.

Q.3: Which topics are covered in NCERT Class 10 Science Chapter 2?
Ans: The topics covered under chapter 2 are:

  • 2.1 Understanding The Chemical Properties Of Acids And Bases
  • 2.2 What Do All Acids And All Bases Have In Common?
  • 2.3 How Strong Are Acids Or Base Solutions?
  • 2.4 More About Salts

Q.4: Are the NCERT Solutions for Class 10 Science Chapter 2 available only online?
Ans: No, Students can download the CBSE Solutions for Class 10 Science Chapter 2 in PDF format to practice the questions in offline mode as well.

Q.5: Why should students refer to NCERT Solutions for Class 10 Science Chapter 2 by Embibe?
