Question
Given below are two statements: Statement I : Aqueous solution of K2Cr2O7 is preferred as a primary standard in volumetric analysis over Na2Cr2O7 aqueous solution. Statement II : K2Cr2O7 has a higher solubility in water than Na2Cr2O7. In the light of the above statements, choose the correct answer from the options given below : (A) Both Statement I and Statement II are true (B) Statement I is false but Statement II is true (C) Both statement I and statement II are false (D) Statement I is true but statement II is false
💡 Solution & Explanation
(i) Potassium dichromate is used as a primary standard in volumetric analysis. (ii) K2Cr2O7 is less soluble in water than Na2Cr2O7. Sodium salt has a greater solubility in water and is extensively used as an oxidising agent in organic chemistry.
