Textbook Question
Chapter 3, Problem 81E
Salts containing the phosphate ion are added to municipal water supplies to prevent the corrosion of lead pipes.
- Based on the PK, values for phosphoric acid (Pka1 = 7.5 × 10-3 Pka2 = 6.2 × 10-8, pka3 = 4.2 × 10-13) what is the Kb value for the PO43- ion?
- What is the pH of a 1× 10-3 M solution of Na3PO4 (you can ignore the formation of H2PO4- and H3PO4)?

It is др defined as Br=-()=-(200²)T' (a) You might wonder why there is a negative sign in this formula. What does it mean when this quantity is positive and what does it mean when this quantity is negative? (b) Derive the formula for the isothermal compressibility of an ideal gas (it is very simple!)
