When 0.6 g of an organic acid dissolved in 200 mL of water is extracted with 50 mL of ether, it is found on analysis, that 0.4 g of the organic acid goes into the ether layer. Which of the following represents the correct ratio of the solubility of the acid in ether and water?

Question

When 0.6 g of an organic acid dissolved in 200 mL of water is extracted with 50 mL of ether, it is found on analysis, that 0.4 g of the organic acid goes into the ether layer. Which of the following represents the correct ratio of the solubility of the acid in ether and water? (A) (Sether/Swater) = 0.125 (B) (Sether/Swater) = 0.5 (C) (Sether/Swater) = 2 (D) (Sether/Swater) = 8

Tardigrade Admin · Accepted Answer

Solubility in water = 0.2/200 mL Solubility in ether = 0.4/50 mL or 1.6/200 mL ⇒ (Sether/Swater) =(1.6/0.2) = 8

Q. When 0.6 g of an organic acid dissolved in 200 mL of water is extracted with 50 mL of ether, it is found on analysis, that 0.4 g of the organic acid goes into the ether layer. Which of the following represents the correct ratio of the solubility of the acid in ether and water?

$\frac{S _{e t h er}}{S _{w a t er}} = 0.125$

$\frac{S _{e t h er}}{S _{w a t er}} = 0.5$

$\frac{S _{e t h er}}{S _{w a t er}} = 2$

$\frac{S _{e t h er}}{S _{w a t er}} = 8$

Solubility in water = 0.2/200 mL
Solubility in ether = 0.4/50 mL or 1.6/200 mL
$\Rightarrow \frac{S _{e t h er}}{S _{w a t er}} = \frac{1.6}{0.2} = 8$

Swater​Sether​​=0.125

Swater​Sether​​=0.5

Swater​Sether​​=2

Swater​Sether​​=8

Solubility in water = 0.2/200 mL Solubility in ether = 0.4/50 mL or 1.6/200 mL ⇒Swater​Sether​​=0.21.6​=8

$\frac{S _{e t h er}}{S _{w a t er}} = 0.125$

$\frac{S _{e t h er}}{S _{w a t er}} = 0.5$

$\frac{S _{e t h er}}{S _{w a t er}} = 2$

$\frac{S _{e t h er}}{S _{w a t er}} = 8$

Solubility in water = 0.2/200 mL
Solubility in ether = 0.4/50 mL or 1.6/200 mL
$\Rightarrow \frac{S _{e t h er}}{S _{w a t er}} = \frac{1.6}{0.2} = 8$
