Assume a Solution Is Prepared by Adding 1 C Term
B) Neither the Dissociation of Water nor The 10-3
Multiple Choice
Assume a solution is prepared by adding 1.0 x 10-3 moles of a weak monoprotic acid (Ka = 2.0 x 10-4) to enough water to give a liter of solution. If you want to compute the H3O+ ion concentration with an error of 5% or less, you can legitimately ignore:
A) both the contribution of the dissociation of water and the C term.
B) neither the dissociation of water nor the C term.
C) the dissociation of water but not the C term.
D) the C term but not the dissociation of water.
E) You can't compute the H3O+ concentration with an error of less than 5%.
