Part A: CH₃COCH₃
CH₃COCH₃ is a nonelectrolyte, which means it does not dissociate when it dissolves in water. Therefore, the only solute present will be the undissociated CH₃COCH₃.
Part A: In an aqueus solution there are three solute particles: H3O+, HCOO- and HCOOH
Part B: HCOOH(aq) + H2O(l) ⇄ HCOO-(aq) + H3O+(aq)
Weak acids don't completely ionize in solution, for this reason, a formic acid solution contains un-ionized acid, it means there are many intact molecules of formic acid and only a fraction of the dissolved molecules ionize to form H3O+(aq) and HCOO-(aq).
The chemical equation is:
HCOOH(aq) + H2O(l) ⇄ HCOO-(aq) + H3O+(aq)
The double arrows in this equation indicate that the ionization can occur in both the forward and reverse directions.
it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
