Molecular Form?

Postby Antonio Melgoza 2K » Mon Nov 23, 2015 5:59 pm

For question J.5 in the homework, it says to leave the substance in its molecular form if the substance is a weak acid or base. What does it mean by molecular form and can I see an example?

If a substance is a weak acid or base, then it doesn't completely dissociate and that's why you would leave it in its molecular form.
For part a) HF is a weak acid so it would stay as HF(aq) in the ionic equation (writing it as HF is the molecular form)
NaOH is a strong base and therefore dissociates into Na+ (aq) and OH- (aq)
