Homework Statement
A cylindrical solenoid 30 cm long with a radius of 8 mm has 400 tightly-wound turns of wire uniformly distributed along its length (see the figure). Around the middle of the solenoid is a two-turn rectangular loop 3 cm by 2 cm made of resistive wire having a...
The Na+ involved another problem I presented a while back. I think it was bubbling CO2 through an NaCl solution, then adding Na(OH).
The logK's I've given are the same as those given by the professor.
You are totally right about being explicit. It's easy to lose track of what...
Sorry to confuse, I should have been clearer.
α0 is the alpha value ( relative concentration) of the free acid. I had been attempting to use a generic formula in a text for the composition of polyprotic acids as a function of pH given by:
For a diprotic acid say:
α0= [H+]2 / CT...
Setting up equations for equilibria
The Attempt at a Solution
I have tried setting up mass balances and doing various substitutions to obtain an α0 that I could solve for iteratively, but so far I've gotten nowhere. I've found alpha plots for the speciation of Cr(VI) in several...
So, I'm assuming no Sodium Bicarbonate or Carbonate is formed during this process.
I found the concentrations of the species by basic ICE diagram.
Mostly, I need to know how to approach this problem conceptually . I'm assuming the effect of NaCl on the CO2-->H2CO3-->HCO3- --> CO3--...
Thanks Borek. I think I'll work on the numerical approach, maybe Newton-Raphson. This class, I think, was a mistake. It's a combined grad/undergrad class, and I've spent so much time reading Analytical Chem and Thermodynamics (classes I have NOT taken) that I've neglected my physics class...
Hi, this is some Geochemistry homework. We were not really given much information on how to approach this problem. I treated it as a diprotic acid H2CrO4, and made an alpha plot using the equations given using the constants K only for the fully protonated and deprotonated species. I'm not...
