CBSE Class 10 Science Chemistry Chapter 2 - Acids, Bases, and Salts

NCERT Solutions for Class 10 Science Chemistry for this chapter gets you to know better about the food around you. The sour and bitter taste of the food is due to the presence of acids, bases and salts in them respectively. The following are the key points discussed in this chapter:

Importance of pH in everyday life

·         pH change and survival of animals

·         pH in our digestive system

·         pH change  - Cause of tooth decay

 

pH of Salts

·         Salts of strong acid and a strong base are neutral, with a pH value of 7.

      For Example: NaCl, Na2SO4

·         Salts of strong acid and weak base are acidic, with a pH value less than 7.

      For Example: Ammonium chloride solution has pH value of 6.

·         Salts of weak acid and strong base are basic, with a pH value more than 7.

      For Example: Sodium carbonate solution has a pH value of 9.

 

Common Salt

·         Common salt is a neutral salt and can be prepared in the laboratory by the reaction of sodium hydroxide and hydrochloric acid.

         NaOH(aq)       + HCl(aq)    →         NaCl(aq)  +   H2O(aq)

·         It is an important raw material for products of daily use such as NaOH, baking soda, washing soda and bleaching powder.

 

Sodium Hydroxide

·         Sodium hydroxide is produced by the electrolysis of an aqueous solution of sodium chloride (called brine).

·         The process is called the chlor-alkali process because of the products formed, i.e. ‘chlor’ for chlorine and ‘alkali’ for sodium hydroxide.

2NaCl(aq)       + 2H2O(aq)       →       2NaOH(aq)     +    H2(g)  + Cl2(g)

 

Bleaching Powder

·         It is produced by the action of chlorine on dry slaked lime [Ca(OH)2].

Ca(OH)2    +     Cl2                             →       CaOCl2     +    H2O

·         It is represented as CaOCl2


Uses

·         For bleaching cotton and linen in the textile industry and for bleaching wood pulp in the paper industry.

 

·         Used for disinfecting drinking water to make it free of germs.

NCERT Solutions for CBSE Class 10 is just the appropriate resort for the preparation of CBSE Class 10 Science Chemistry. Refer to CBSE sample paper Class 10 for the questions that can be asked in exams from this chapter.

Chemical Properties of Metals

Reaction of Metals with Oxygen

Almost all metals react with oxygen to form metal oxides.

i.        Sodium and potassium are the most reactive and react with oxygen present in the air at room temperature to form the oxides.

ii.      Magnesium does not react with oxygen at room temperature, but on heating, it burns in the air with intense light and heat to form magnesium oxide.

 

Reactions of Metals with Acids

Metals react with acids to form salt and hydrogen gas.

i.        Metals react with dilute hydrochloric acid to give metal chloride and hydrogen gas.

      Mg + 2HCl → MgCl2    + H2                    

ii.      Metals react with sulphuric acid to form metal sulphate and hydrogen gas.

      Fe + H2SO4 → FeSO4   + H2

iii.    Metals react with nitric acid, but hydrogen gas is not evolved since nitric acid is a strong oxidising agent. So, it oxidises the hydrogen to water and itself gets reduced to a nitrogen oxide.

      But magnesium and manganese react with dilute nitric acid to evolve hydrogen gas.

      Mg + 2HNO3 → Mg (NO3)2    + H2

      Mn + 6HNO3  → Mn (NO3)2   + H2

 

Reactivity Series

The arrangement of metals in the order of decreasing reactivities is called the reactivity series of metals.

 

Reactions of Metals with Solutions of Other Metal Salts

A more reactive metal displaces a less reactive metal from its salt solution.

For example:

When an iron nail is placed in a copper sulphate solution, the blue colour of CuSO4 fades away slowly and a reddish brown copper metal is formed.

CuSO4(aq) + Fe(s)  → FeSO4(aq)  + Cu(s)

 

Reaction of Metals with Chlorine

Metals react with chlorine to form metal chlorides.

For example:

Sodium readily reacts with chlorine to form ionic chloride called sodium chloride.

2Na(s)   + Cl2(g) → 2NaCl(s)

Properties of Ionic Compounds

·         Ionic compounds are hard solids, due to the strong force of attraction between the positive and negative ions.

·         They are generally brittle and break into pieces when pressure is applied.

·         Ionic compounds have high melting and boiling points, since a large amount of energy is required to break the strong intermolecular attractions.

·         They are soluble in water, but insoluble in solvents such as kerosene, petrol, etc.

 

·         They do not conduct electricity in a solid state, because electrostatic forces of attraction between ions in the solid state are very strong but conduct electricity in the fused (or in the aqueous state) because these forces weaken in the fused (or in solution) state so that their ions become mobile.
