Painkillers Morphine is an e ective painkiller but is also highly addictive. Codeine is a popular prescription painkiller because it is much less addictive than morphine. Codeine contains a basic nitrogen atom that can be protonated to give the conjugate acid of codeine.

Calculate the pH of a 0.115 M solution of morphine if its pKb = 5.79.

Calculate the pH of a 3.42 × 10–4 M solution of codeine if the pKa of the conjugate acid is 8.21.

8. What volume of concentrated nitric acid (HNO3) would you need to dissolve in water to prepare 500.00 mL of a HNO3 solution which has a pH = 1.75? The density of concentrated nitric acid is 1.50 g/mL and is 68 wt% HNO3?

9. Morphine is an effective pain killer but also highly addictive. Calculate the Kb and pKb of a 0.45 M solution of morphine if its pH = 10.93.

A 1.0 L buffer solution contains 0.187 M HC2H3O2 and 0.187 M NaC2H3O2. The value of Ka for HC2H3O2 is 1.8×10−5. Because the initial amounts of acid and conjugate base are equal, the pH of the buffer is equal to pKa=−log(1.8×10−5)=4.74. Part A Calculate the new pH after adding 0.019 mol of solid NaOH to the buffer.
