(a)

Interpretation Introduction

Interpretation: The formation reaction of CuX32,CuX2,Cu+ , volume and concentration of NaX,CuNO3 is given. The concentration of each CuX32,CuX2,Cu+ ion at equilibrium is to be calculated from the given forward constants.

Concept introduction: At equilibrium, the equilibrium constant expression is expressed by the formula,

K=ConcentrationofproductsConcentrationofreactants

Explanation of Solution

To determine: The concentration of CuX32 from the given condition.

The initial concentration of Cu+ in a solution is 1.0×103M_ and the initial concentration of X is 5.0M_ .

Given

Concentration of NaX before reaction is 10.0M .

Concentration of CuNO3 before reaction is 2.0×103M .

Volume of NaX is 50mL .

Volume of CuNO3 is 50mL .

It is assumed that the concentration of Cu+ and X is same as the concentration of CuNO3 and NaX . Hence, concentration of Cu+ and X is,

[Cu+]=2.0×103M[X]=10M

Formula

The initial concentration of compound is calculated using the formula,

Initialconcentration=Volumeofcompound×Givenconcentration(Volumeoforiginalsolution(mL)+(Volumeofcompoundadded(mL)))

Substitute the values of volume, given concentration of Cu+ and volume of original solution in the above equation.

Initialconcentration=Volumeofcompound×Givenconcentration(Volumeoforiginalsolution(mL)+(Volumeofcompoundadded(mL)))=50mL(2.0×103)M50mL+50mL=1
