JEE Chemistry Question: Tartaric Acid and Washing Soda


Introduction

The question describes an experiment where equal amounts of tartaric acid and washing soda are dissolved separately in 100 cc of water.


Options


  • Option 1: Equal amount of acid and base respectively

  • Option 2: Equally acidic and basic substance respectively

  • Option 3: Acidity in one and basicity in the other are not equal

  • Option 4: Equal magnitude of the quantity |pH-7|



Explanation

The correct option is Option 3: Acidity in one and basicity in the other are not equal.


  • Tartaric acid is an acid, and it will release H+ ions in water, making the solution acidic.

  • Washing soda is a base (sodium carbonate), and it will release OH- ions in water, making the solution basic.

  • When equal amounts of the acid and base are dissolved in water, the acidity in one and basicity in the other are not equal.

  • Therefore, the pH of the solutions will be different, and the drops of the acid solution and the basic solution will not be equally acidic and basic respectively.

  • The correct answer is not Option 1 because the amount of acid and base in the drops is not equal.

  • The correct answer is not Option 2 because the drops do not contain equally acidic and basic substances, as explained above.

  • The correct answer is not Option 4 because the magnitude of the difference between the pH and 7 will depend on the pH values of the solutions, which are not necessarily equal.
