A solution is made by dissolving 15.0 g sodium hydroxide in approximately 450 mL water. The solution becomes quite warm, but after it is allowed to return to room temperature, water is added to bring the volume to 500.0 mL of solution. (a) Calculate the pH and pOH in the final solution. (b) Why would we wait for it to return to room temperature? (c) If the mass of the water used to initially dissolve the sodium hydroxide were exactly 450 g and the temperature of the water increased by 8.865 C, how much heat was given off by the dissolution of 15.0 g of solute? Assume the specific heat of the solution is 4.184 J/g. K. What is the molar heat change for the dissolution of sodium hydroxide (known as the enthalpy of solution, Hsol)?

What is the [H3O+] of 0.10 M propanoic acid (CH3CH2COOH, can simplify to HPr) (Ka= 1.3x10−5)?Calculate the pH of a 0.050 M solution of ethylamine (C2H5NH2, Kb= 6.4 x10–4).
Arrange the following 0.1 M solutions in order of increasing pH NaCH3COO, HCl, HCN, NaOH, NH3, NaCN, KNO3, NH4Cl, H2SO3, NaHCO3, Na3PO4 and CH3COOH. (give a brief explanation as to why it is the position, e.g. strong acid/base, larger Ka or Kb etc.) Hint: read through the ‘useful information at the end of the lab’ In the case of the diprotic species (e.g. H2SO3 the major contribution to acidity comes from the first proton loss. The second typically a makes a much smaller contribution) H2SO3: This is a weak acid with Ka1 = 1.7 x 10-2. (This is the dissociation constant associated with the loss of the first proton) CH3COOH: This is a weak acid with Ka = 1.8 x 10-5. HCN: This is a weak acid with Ka = 5.8 x 10-10. Hydrogen carbonate is a weak base with Kb = 2.3 x 10-8. NH3: This is a weak base with Kb = 1.8 x 10-5. Na3PO4: The phosphate ion is a weak base with Kb = 2.2 x 10-2
