In Part A, a 15.00 mL aliquot of a 0.175 mol L-1 2,2-dimethylpropanoic acid solution was titrated to its equivalence point with 24.3 mL of 0.108 mol L-1 NaOH solution. At the equivalence point, all of the weak acid, 2,2-dimethylpropanoic acid, is converted to its weak conjugate base, 2,2-dimethylpropanoate. What is the pH at this equivalence point? O 5.073 O 7.067 O 8.970 O 8.927 O 5.030

Q) Drinking water may contain several unwanted ions such as phosphate ions. In order to remove the phosphate ions from the drinking water, a solution of calcium hydroxide can be added. As a result, a solid Ca5OH(PO4)3 is formed and isolated by filtration and a hydroxide ion are also formed. The reaction for this process is below: 5 Ca(OH)2 (aq) + PO43- (aq) → Ca5OH(PO4)3 (s) + OH- (aq) a) If 3.00 mL of 0.100 M calcium hydroxide is mixed with 4.00 mL of an aqueous solution of 0.0800 M phosphate ions (PO43-).
