A chemical industry generates wastewater that contains ethanol 130 mg L and methanoic or formic acid 400 mg L If the discharge flow is 80 L s what will be the BOD of the wastewater due to these two substances B water contains a concentration of sulfate ions of the order of 1 0 x 10 3 M and of carbonate ions of 1 0 x 10 5 M It is desired to precipitate the sulfate as strontium sulfate and for this SrCl2 0 is used 1 mol dm3 a Will this procedure work Prove with calculations Data Kps 5 6 x 10 10 for strontium carbonate and 3 4 x 10 7 for strontium sulfate
