1. [12] Balance the following reaction and concisely answer questions: a. Balance the reaction KAI(SO): + H2O = Al(OH)o) + K+ + SO42-+ H+ b. The above equation describes a common coagulation process using alum in water treatmernt plants. After applying the alum, how does the alkalinity change in the water (increase/ decrease/ no change) and why? process using alum in water treatment 2. [12] If 200 mg of HCl is added to water to achieve a final volume of 1.00 L, what is the final pH? ![1. [12] Balance the following reaction and concisely answer questions: a.

Solution
1. KAl(SO4)2 +3 H2O = Al(OH)3 + K+ + 2SO42- +3 H+
After applying the alum The alkanity in the water Decreases because of the release of H+ ions. H+ ion decreases the Ph, hence Increasing Acidity or decreasing Alkalinity.
