Calculate the ratio of dihydrogen phosphate to hydrogen phosphate in the blood at pH 7.4. The Ka = 6.3 x 10 -8 5. 2. For a weak acid with a pKa of 6.0 calculate the ratio of conjugate base to acid at a pH of 5.0
My dilemma is that I'm unsure on how to find the actual limiting reactant, and what information I should use. There's too much given; but from my introspection, we only need 1-Octene and the Pt catalyst
