Question 1

For H3PO4, Ka1 = 7.3 × 10–3, Ka2 = 6.2 × 10–6, and Ka3 = 4.8 × 10–13.  An aqueous solution of Na3PO4 therefore would be
◦ neutral
◦ basic
◦ acidic

Question 2

For maleic acid, HOOCCH=CHCOOH, Ka1 = 1.42 × 10–2 and Ka2 = 8.57 × 10–7.  
What is the concentration of maleate ion (OOCCH=CHCOO) in a 0.150 M aqueous solution of maleic acid?
◦ 8.57 × 10–7 M
◦ 2.79 × 10–6 M
◦ 1.86 × 10–5 M
◦ 4.60 × 10–2 M
◦ 1.19 × 10–1 M
