Choose an option
Show full solutionCorrect option: B
Correct answer
BSol A is positively charged and Sol B is negatively charged.
Step-by-step explanation
In first case the given compounds have same anion but different cations having different charge hence they will precipitate negatively charged sol i.e. 'A'.
In second case the given compounds have similar cation but different anion with different charge. Hence they will precipitate positively charged sol. i.e. ' '.
