## 5. How would you use the Henderson–Hasselbalch equation to calculate ...

17 mei 2016 · ... molar masses of the two compounds to determine how ... The solution is said to be 0.800% by mass pyridine and 0.990% by mass pyridinium chloride.

Here's what I would do. You're dealing with a buffer solution that contains pyridine, "C"_5"H"_5"N", a weak base, and pyridinium chloride, "C"_5"H"_5"NHCl", the salt of its conjugate acid, the pyridinium cation, "C"_5"H"_5"NH"^(+). In order to be able to use the Henderson - Hasselbalch equation, which for a buffer that contains a weak base and its conjugate looks like this color(blue)(|bar(ul(color(white)(a/a)"pOH" = pK_b + log((["conjugate acid"])/(["weak base"]))color(white)(a/a)|))) you will need to determine the concentrations of pyridine and of the pyridium cation. The value of the base dissociation constant, K_b, for pyridine can be found here K_b = 1.7 * 10^(-9) http://www.bpc.edu/mathscience/chemistry/table_of_weak_bases.html Now, the problem doesn't provide you with the density of the solution; however, because you're dealing with such small amounts of pyridine and pyridinium chloride, you can assume that the density of the solution is approximately equal to that of water. To keep the calculations simple, you should take rho_"solution" ~~ rho_"water" ~~ "1 g mL"^(-1) Now, let's assume that you're dealing with a "1-L" sample of this buffer solution. Since you know that color(purple)(|bar(ul(color(white)(a/a)color(black)("1 L" = 10^3"mL")color(white)(a/a)|))) you can say that this sample will be equivalent to 1 color(red)(cancel(color(black)("L"))) * (10^3"mL")/(1color(red)(cancel(color(black)("L")))) = 10^3"mL" Now, this sample will have a mass of 10^3color(red)(cance...
