Difference of OH- in Strong vs Weak Bases

[clavin]

is there any difference in oh- from a strong base than from a weak base apart from concentration?
second
lets say we have this reaction
ch3cooh + oh- => ch3coo- + h2o
in this reaction my book says the reaction will go to completion
but isn't acetic acid a weak acid. so shouldn't the disassociation should be partial
therefore why does the reaction go to completion?
also one more example
ch3cooNa=> ch3coo- + Na+
here again the disassociation is full
as Na+ comes from a strong acid
so why the dissociation extent of Na affect that of ch3coo-

 

[Borek]

All OH^- are identcial, and indistinguishable.

No such thing as ch3cooh - please write formulas correctly.

Neutralized acetic acid slightly hydrolizes, so stating that the reaction goes to completion is an aproximation - but a good one.

Na⁺ doesn't come from an acid. I have no idea what you are asking about.
