QNEET-2019-Ch-747: NEET 2019 Chemistry - Class 12 NEET-2019-Ch-747 Solution: Which mixture of the solution will lead to the formation of…
Which mixture of the solution will lead to the formation of negatively charged colloidal sol.? 50 mL of 2 M + 50 mL of 1.5 M KI 50 mL of 0.1 M + 50 mL of 0.1 M KI 50 mL of 1 M + 50 mL of 1.5 M KI 50 mL of 1 M + 50 mL of 2 M KI
Multiple Choice Options
- A 50 mL of 2 M AgNO 3 + 50 mL of 1.5 M KI
- B 50 mL of 0.1 M AgNO 3 + 50 mL of 0.1 M KI
- C 50 mL of 1 M AgNO 3 + 50 mL of 1.5 M KI
- D 50 mL of 1 M AgNO 3 + 50 mL of 2 M KI
Step-by-Step Verified Solution
AgNO 3 + KI _ AgI + KNO 3
If KI is in excess then negatively charged colloid,
[AgI]I �
is formed. Whereas, if AgNO 3 is in excess
positively charged colloid AgI/Ag + will form.
