JEE Main Chemistry question
Not in JEE Main or NEET syllabus
Match the following:
| Column-I | Column-II | |---|---| | (A) Dialysis | (p) Precipitate converts to colloidal solution | | (B) Peptization | (q) Precipitation of colloidal solution | | (C) Flocculation | (r) Protective power | | (D) Gold number | (s) Purification of colloidal solution |
Answer: (A)
Solution
Dialysis is the process of purifying a colloidal solution by removing dissolved ionic impurities through a membrane, so A→s; peptization converts a freshly formed precipitate into a colloidal solution, so B→p;
