Question

List of Electrolytes:

NaCl, H3PO4, HC2H3O2(also written as CH3COOH), H3BO3, C2H6O2, CaCl2, CH3OH, HCl, and AlCl3, Tap Water and DI Water

3. a) What can be concluded about how your acids are classified (are they strong, weak, or non-electrolytes?) b) Write a balanced equation for the dissociation of each of the acids, as was done for the ionic compounds. Here assume complete dissociation, disregarding the conductivity data for now. (HINT: Remember polyatomic ions! There should not be more than two different kinds of ions for each equation). c) Is it correct to assume complete dissociation for all acids? Considering the conductivity value for each acid, make a note next to its dissociation equation in (b) whether "complete dissociation is observed", "partial dissociation is observed", or "little or no dissociation is observed." Using these results, label each acid also as a strong, weak, or non-electrolyte. d) Can a person predict whether an acid will be a strong, weak, or non-electrolyte based only on its chemical formula? For example, if all that is known is that citric acid has the formula H3C&H5O7, can a person predict with no other knowledge whether this acid will be a strong, weak or non-electrolyte? Explain
