Why do I add strong acid (e.g. HCl) to the salt of a weak acid (ammonium acetate) to bring UP the pH of the buffer solution from the pKa
A buffer solution contains 0.23 mol of carbonic acid (H2CO3) and 0.55 mol of sodium hydrogen carbonate (NaHCO3) in 2.10 L. The Ka of carbonic acid (H2CO3) is Ka = 4.3e-07. (a) What is the pH of this buffer? pH = (b) What is the pH of the buffer af..
Propose a structure for an amine of formula C4H9N, which does not liberate a gas when treated with NaNO2 and HCl, and has IR absorptions at 917 cm-1, 990 cm-1, and 1640 cm-1, as well as an N-H absorption at 3300 cm-1. The 13C NMR spectrum is as fo..
