Figure 15-3 outlines the classic scheme for separating a mixture of insoluble chloride salts from one another. Explain the chemistry involved in the various steps of the figure.
Amino acids are an important group of compounds. At low pH, both the carboxylic acid group (CO2H) and the amine group (NHR) are protonated. However, as the pH of the solution increases (say, by adding base), the carboxylic acid proton is removed, usually at a pH between 2 and 3. In a middle range of pHs, therefore, the amine group is protonated, but the carboxylic acid group has lost the proton. (This is called a zwitterion.) At more basic pH values, the amine proton is dissociated. What is the pH of a 0.20 M solution of alanine hydrochloride, [NH3CHCH3CO2H]Cl?
8-61 Can 100 of 0.1 M phosphate buffer at pH 7.2 act as an effective buffer against 20 mL of 1 M NaOH?
what is the pH of a solution prepared by mixing 50.0 mL of 0.125 M amonia and 25.0 mL of 0.100 M hyrogen chloride (The acid dissociation constant of amonnium ion is 5.70x10-10)
Selenic acid, H2SeO4, is a diprotic acid that actually is a strong acid for the donation of its first proton and has a pKa2 = 1.7. What will be the Ka and the chemical equation for showing the donation of the second proton? (hint: products will be H3O+ and SeO42-) I take 2.00 g the pure compound and dilute it to 100.0 mL of solution. Find the initial concentration and use two ICE tables to show the equilibrium concentrations of [H3O+], [OH-], [HSeO42-] and [SeO42-]. What will be the concentration of H2SeO4? (hint: no math is necessary here as this is a strong acid).
