Question number one
### Question 1 Find the pH at the end point in the titration of 0.2 M potassium acid maleate, \( KHM \), with 0.2 M NaOH. Maleic acid, \( H_2M \), \( k_{a1} = 1.2 \times 10^{-2} \); \( k_{a2} = 9 \times 10^{-7} \). ### Question 2 The digestion of a 0.1417 g sample of a phosphorus-containing compound in a mixture of \( HNO_3 \) and \( H_2SO_4 \) resulted in the formation of \( PO_4^{3-} \).
