Question

Assertion(A): A colloidal sol of Al(OH)3 is more readily coagulated by 0.1M NaCl than by 0.1 M Na2SO4 .Reason(R) The coagulation power of an electrolyte is related to the concentration of the active ions

Answer 1

Answer:

hi there!!

Explanation:

happy helping ❤️

I guess both the statements are false.

reason:

• Al has +3 charge, NaCl has -1 cl charge and Na2so4 has so4 2- charge. comparitively so4 2- can make the solution coagulate more easier. more the charge, more is the coagulation power.
• And coagulation power is not related to concentration of ions, it depends on charge and magnitude of charge of the ion.
