The of an acid and a base is determined by how completely they dissociate in water?
The _____________ of an acid and a base is determined by how completely they dissociate in water. strength
The strength of an acid and a is determined by how completely they dissociate in water.?
base
How do strong and weak bases dissociate or ionize?
Strong bases dissociate or ionize completely. Weak bases dissociate or ionize only partially. The degree to which they ionize/dissociate is given by the Kb for each weak base.
Does a strong base dissociate more completely in water then a weak base does?
Yes. That's essentially the definition of "strong base".
Why is ammonium hydroxide a weak base?
So, ammonium hydroxide is a weak base. Weak base means that it dissociate slightly in water, that is, it does not dissociate 100% in water. This is because, when ammounium hydroxide reacts with water it forms hydrogen ions. But as the reaction is very revesible it will never react completely with water, that is, it will never dissociate completely with water. Thus, it is a weak base.

What cause an acid or base to dissociate?
The polar water molecules pull apart the ions of the acid or base
Ammonia is a weak base because?
The ions of ammonia do not fully dissociate in aqueous solution.
What is the relationship of a strong acid and a strong base?
Strong acids dissociate almost completely making H+ ions while strong bases also dissociate completely making OH-
Do weak acids completely dissociate like strong acids but then instantly change to base in water?
Nope. They just don't fully dissociate. The molecules don't break apart completely.
What does a strong base do in solution?
becomes fully ionized They dissociate fully / ionize fully into OH- ions.
What will happen if a base is added to water?
Bases dissolve in water and donate hydroxide ions to solution. It will dissociate.
Why do acids or bases dissociate?
polar water molecules pull apart the acid or base by pulling on the charged ions.
