Question
Four groups of students are studying with different samples of alkali metal halides as given below. Group A: NaCl, Group B: NaBr, Group C: KCl, Group D: KBr. If all the four groups dissolved 0.1 moles of their salt in some water and then treated with the excess of acidified AgNO3 solution, then which of the following statement(s) is/are correct regarding the mass of precipitate formed?
Options
A.All the four groups will obtain the same mass of precipitate
B.Group A and C will obtain the same mass of precipitate
C.Group B and D will obtain the same mass of precipitate
D.Group A and B will obtain the same mass of precipitate
Solution
Group A and C ⇒ 0.1 mole AgCl
Group B and D ⇒ 0.1 mole AgBr
