Answer #1

The adsorption of oxalic acid in charcoal is a verification of Langmuir Adsorption Isotherm.

Adsorption is a phenomena in which particles gets attached to the surface of solids . The greater the surface given by a solid, if it is avoidally dispersed and hence colloids passes the adsorption properties.

In this adsorption process, the adsorption happening is Langmuir adsorption isotherm. this adsorption depends on specific area of the solid,the equilibrium solute concentration in solution is lower of gaseous adsorption , the nature of the adsorbate and temperature. The equation can be represented as:

   x=( K1K2C)/(1+K1C)

x= mass of solute

m=mass of adsorbent

K1K2 = constant

I collect the oxalate anion containing complex (the acid form of which reacts with potassium permanganate to form carbon dioxide and water, while it itself forms solubilized MN+2) of an unknow calcium containing sample and, following precipitation to purify the calcium oxalate, I redissolve it into an acidic solution (which converts the oxalate in oxalic acid). I add to this 16ml of .015 M KMnO6 solution, at which point my indicator suggests that no oxalic acid remains. What was the...

Why aren't buffers made with 1:1 ratio of acid and conj.base? Wouldn't 1:1 give a better buffering capacity both ways? for example the PBS buffer only has 0.24g/L of KH2PO4 while Na2HPO4 has 1.42g/L. So why are they made like that? Isn't it better when both of them have the same g/L ? This also means that the PBS buffer is better at resisting strong acidic stuff correct?
