Aluminum sulfate (Al2(SO4)3) is an iron-based coagulant that is used during water and wastewater treatment to enhance removal of solids. You may assume that when ferric chloride is added to water the following reaction occurs: 3. Al2(SO4)3 → 2 Al3+ + 3 SO,2- How much aluminum sulfate is required (in grams) to prepare 500 mL of 3,000 mg/L Al2(SO4)3 solution? а. b. How much aluminum sulfate is required (in grams) to prepare 500 mL of 3,000 mg/L Al2(SO4)3 solution if the aluminum sulfate chemical stock is 73% pure?

Question
Transcribed Image Text:Aluminum sulfate (Al2(SO4)3) is an iron-based coagulant that is used during water and wastewater
treatment to enhance removal of solids. You may assume that when ferric chloride is added to water the
following reaction occurs:
3.
Al2(SO4)3 → 2 Al³+ + 3 SO,²-
How much aluminum sulfate is required (in grams) to prepare 500 mL of 3,000 mg/L Al>(SO4);
solution?
а.
b. How much aluminum sulfate is required (in grams) to prepare 500 mL of 3,000 mg/L Al2(SO4)3
solution if the aluminum sulfate chemical stock is 73% pure?
What is the aluminum (Al³*) concentration (in mg/L) in the solution?
d. What is the sulfate (SO,?) concentration (in mg/L) in the solution?
с.
