Question

The charge on as2s3 sol is due to adsorption of

Answer 1

Hello Dear,

Your answer is here,

→→→→→→→→→→→→

The Answer is ↔  S²⁻ 


Reason/Explanation →

As we know As₂S₃ is a negatively charged solution .

In this solution the negative charge is due to adsorption of S²⁻ ion . 


For Example-


For the coagulation of the As₂S₃(Which is negatively charged solution) , We need positively charged solution ,So the most flocculating solution will be AlCl₃ because Al has 3⁺ charge on it.

Answer 2

Thanks for the question!

It is definitely a very interesting question to solve and do some brainstorming.

**************************************************



As₂S₃ is a negatively charged solution and the negative charge is due to adsorption of S2- ions on the sol.

It follows the Hardy-Schulz law which states : 'the greater the valence of the flocculating ion, the greater will be its coagulating property."
