Explanation:

Given 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.

• We need to find the ratio of the solubility of the acid in ether and water. Now 0.6 g of organic acid is dissolved in 200 ml of water and is extracted with 50 ml of ether, and so 0.4 g of organic acid goes into ether layer.
• So we have solubility in water will be 0.6 – 0.4 = 0.2
•                       So we get 0.2 g / 200 ml
• Solubility in ether will be 0.4 g / 50 ml
•                                          = 0.4 x 4 / 50 x 4  
•                                         = 1.6 / 200 (since we get equal denominator)
• So we have 0.2 / 200 and 1.6 / 200
• Therefore the ratio of solubility of the acid in ether and water will be
•             Solubility in ether / Solubility in water
•                       = 1.6 / 0.2
•                       = 16 / 2
•                       = 8
