Answer:
Activity 2.13 NCERT Class 10 Science, Chapter 2 Acids, Bases, and Salts
Procedure:
Activity 2.13 asks us to write the formula of various salts, their source and group them into their families.
Answer:
Formula:
Potassium sulphate: K2SO4; Sodium sulphate: Na2SO4; Calcium sulphate: CaSO4; Magnesium sulphate: MgSO4; Copper sulphate: CuSO4; Sodium chloride: NaCl; Sodium nitrate: NaNO3; Sodium carbonate: Na2CO3; Ammonium chloride: NH4Cl.
Acids and bases which forms these salts:
When acids and bases mix, they react vigorously and form respective salt.
Acid + Base ———–> Respective salt
Example:
Sodium hydroxide + Nitric acid ———–> Sodium nitrite.
NaOH + HNO3 ————> NaNO3 + H2O
Acids used:
Sulphuric acid (H2SO4); Hydrochloric acid (HCl), Nitric Acid (HNO3), Carbonic acid (H2CO3).
Bases used:
Sodium Hydroxide (NaOH); Magnesium Hydroxide (Mg(OH)2); Calcium Hydroxide (Ca(OH)2).
Family:
Sodium salts: Sodium sulphate, Sodium chloride, Sodium nitrate, Sodium carbonate.
Similarly, we can group other salts as Potassium salts, magnesium salts, Ammonium Salts, Chloride salts, Sulphate salts, Nitrate salts etc.
