The precipitative gravimetric analysis finds applications in environmental chemistry for precipitation of sulfates from wastewater. There are different steps and conditions required in such a real-life situation unlike the lab experiment dealing with only chlorides. Perform a literature search and discuss the measures

Answer:hydrated lime is used initially to precipate most of the sulfate as gypsum

Explanation:

The most common method for removing sulfate from highly concentrated waste water is the addition of lime which precipitate calcium sulphate

The next step is the addition of CESR reagent to lime water treated precipitate sulfate ... we have the steps as followed: initial surface precipation, metal hydroxide precipitation, final surface precipitation and pH reduction/recarbonation
