The hydrolysis of the weak acid with water, i'll represent acetic acid as just ha.
00:08
It's a weak acid, so it stays together and doesn't dissociate to a significant amount when we're writing these equations.
00:17
It'll react with water, producing hydronium ion and its conjugate base.
00:29
This is the molecular equation it's also the ionic and net ionic equation this doesn't significantly dissociate so there's no spectator ions to cancel so this is all three then for the second one they want the neutralization reaction between the weak acid and sodium hydroxide so so that'll be sodium hydroxide reacting with the weak acid, producing sodium with the conjugate base and water.
01:25
This is the formula equation, more appropriately called formula than molecular equation because because this is not a molecule, but we'll call it what they called it, molecular.
01:40
Then we can rewrite it where the sodium and the hydroxide, this being a strong base, have dissociated, producing a sodium ion, the hydroxide ion, the ha aqueous, the na plus aqueous, this sodium salt dissociates into the conjugate into the sodium ion and the conjugate base and then water stays together and this is the complete ionic equation the net ionic is the same thing but with the sodiums canceling the sodiums being the spectator ions this becomes the net ionic equation and then for the last one the hydrolysis of the conjugate base of the weak acid so if they're talking about the a minus as the conjugate base without its associated sodium they probably want that so they probably mean the naa aqueous a standing for acetate reacting with water as a liquid to produce h a aqueous and hydroxide well it actually be sodium hydroxide...
