Ncert Solutions Chemistry Class 11th

Sodium carbonate is a white crystalline solid which exists as a decahydrate,  This is also called washing soda.

Due to its high dielectric constant, water is a good solvent.

Amphoteric oxides are those which can react with both acid and base

SnO₂, PbO₂ and Al₂O₃ are amphoteric oxide

SiO₂, P₂O₅, CO₂ are acidic oxides

CO, NO and N₂O are neutral oxides

Classical smog contains SO₂

Due to inert pair effect Tl shows +1 oxidation state.

Suspension of slaked lime in water is known as milk of lime

Crude sodium chloride obtained by crystallisation of brine solution contains CaSO₄, Na₂SO₄ and MgCl₂

Beryllium salts are easily hydrolysed

Gypsum : CaSO₄ * 2H₂O

PbS + 4H₂O_2->PbSO₄ + 4H₂O.

Kindly go through the solution

Since V_Real > V_ideal

So, Z = V_Real > 1. V_ideal

Boiling point: $\stackrel{\left(239.7\right)}{N{H}_3}>\stackrel{\left(185.5\right)}{P{H}_3}$  due to hydrogen bonding in NH₃.
