Consider the addition of aluminum sulfate (alum) to water. Using the provided stoichiometry, show that: When 1 mg/L of alum is added to water, 0.5 mg/L of natural alkalinity is consumed. b. When 1 mg/L of alum is added to water, it will react with 0.37 mg/L of hydrated lime а. Ca(OH)2, assuming it is 100% lime. c. When 1 mg/L of alum is added to water, it will react with 0.39 mg/L of 95% hydrated lime Ca(OH)2. d. When 1 mg/L of alum is added to water, it will react with 0.33 mg/L of 85% quicklime as Cao. For this, you will have to consider the fact that 1 mole of Cao gives 1 mol of Ca(Он)2. When 1 mg/L of alum is added to water, it will react with 0.53 mg/L of soda ash as е. Na,CO.

![Chemical coagulation
Consider the addition of aluminum sulfate (alum) to water. Using the provided stoichiometry,
show that:
a. When 1 mg/L of alum is added to water, 0.5 mg/L of natural alkalinity is consumed.
b. When 1 mg/L of alum is added to water, it will react with 0.37 mg/L of hydrated lime
Ca(OH)2, assuming it is 100% lime.
c. When 1 mg/L of alum is added to water, it will react with 0.39 mg/L of 95% hydrated
lime Ca(OH)2.
d. When 1 mg/L of alum is added to water, it will react with 0.33 mg/L of 85% quicklime as
Cao. For this, you will have to consider the fact that 1 mole of Cao gives 1 mol of
Ca(ОН)2.
When 1 mg/L of alum is added to water, it will react with 0.53 mg/L of soda ash as
е.
