For the coagulation of methylene blue sol, the flocculating power of which of the following ion is maximum ?

View answer and explanation

Correct option: A

PO_4^{3 - }

Option A (

PO_4^{3 - }

) is correct because, according to the Hardy-Schulze rule, ions with higher charges have greater flocculating power for oppositely charged sols. Methylene blue sol is positively charged, so a highly negative ion will have the greatest power.
