Butane, C4H10, has been suggested as the refrigerant in household compressors such as those found in air conditioners. (a) To what extent is butane soluble in water? Calculate the butane concentration in water if the pressure of the gas is 0.21 atm. (kH = 0.0011 mol/kg·bar at 25 °C) (b) If the pressure of butane is increased to 1.0 atm, does the butane concentration increase or decrease?

(a)

Interpretation Introduction

Interpretation The concentration of butane in water has to be identified if the pressure of the gas is 0.21atm

Concept introduction:

Solubility of a gas: It is defined as the concentration of the dissolved gas in equilibrium with the substance in the gaseous state.

Henry’s law: The solubility of a gas in liquid is directly proportional to the gas pressure.

Sg= kHPg,where,Sgisthegassolubility(inmol/kg)kHis Henry's constant for gas in water at 25CPg is the partial pressure of the gaseous solute.

Explanation

Given data:

kH(butane gas) = 0.0011 mol/kg.barPbutane=0.21 atm =0.21bar Concentration of  butane gas (Sg)=  ?

According to Henry’s law:

Sg= k

(b)

Interpretation Introduction

Interpretation It has to be identified whether the concentration of butane gas increases or decreases if the pressure increases to 1atm

Concept introduction:

Solubility of a gas: It is defined as the concentration of the dissolved gas in equilibrium with the substance in the gaseous state.

Henry’s law: The solubility of a gas in liquid is directly proportional to the gas pressure.

Sg= kHPg,where,Sgisthegassolubility(inmol/kg)kHis Henry's constant for gas in water at 25CPg is the partial pressure of the gaseous solute.
