Chapter 22, Problem 22.167MP

Interpretation Introduction

(a)

Interpretation:

The balance equation for the disproportionation reaction of NO₂ in water needs to be determined.

Concept introduction:

The main group elements tend to form oxyacid which are usually polyprotic acids like ${\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}{\text{, H}}_{\text{3}}{\text{PO}}_{\text{4}}{\text{, H}}_{\text{3}}{\text{PO}}_{\text{3}}$ etc. and oxides of Nitrogen. A disproportionation reaction can be defined as the chemical reaction in which a substance gets oxidized and also reduced in two separate half-reactions. It results the formation of two other products from the same pertinent element. 

Interpretation Introduction

(b)

Interpretation:

Interpret the molar concentration of ${\text{NO}}_{\text{2}}^{-}$ ion and pH of solution if 500.0 mL of mixture of gases at 25 °C and 753 mmHg was allowed to react with enough water to make 250.0 mL of solution.

Interpretation Introduction

(c)

Interpretation:

The osmotic pressure of the solution in atm needs to be determined.

Interpretation Introduction

(d)

Interpretation:

The grams of lime that would be needed to neutralize the solution needs to be determined.
