Why is it preferable to use a metal ion buffer to achieve pM = 7, rather than just dissolving enough M to give a 10-7 M solution?
Calculate the concentrations of all species in a 0.260 M Na2SO3 (sodium sulfite) solution. The ionization constants for sulfurous acid are Ka1 = 1.4× 10-2 and Ka2 = 6.3× 10-8.
For the following hypothetical elementary step reaction at equilibrium: A in equilibrium with B, and from the ARrhenius equation k= A e^(-Ea/RT), derive the equation : Ln(K1/K2)= delta H/R(1/T2 - 1/T1) in any one of it's forms.
