give some examples of neutral colloids, negatively and positively charged colloids
Examples of negatively colloids-
1. Cadmium sulphide sol.
2. Arsenic sulphide sol.
3. Starch sol.
Examples of positively charged colloids-
1.Haemoglobin sol.
2. Aluminium hydroxide sol.
3. Iron hydroxide sol.
Examples of neutral colloids-
As such no neutral colloids is present but if the solution contain positively charged collides like Aluminium hydroxide sol and it is balanced by equal opposite negatively charged dispersion medium.
