A titration has reached its equivalence point when:

the indicator changes color

the moles of acid = the moles of base

the burette has been emptied

adding more acid or more base will no longer change the pH of the solution

Question

A titration has reached its equivalence point when:
		
the indicator changes color
		
the moles of acid = the moles of base
		
the burette has been emptied
		
adding more acid or more base will no longer change the pH of the solution

I don't think the question is worded very well. The equivalence point is where the acid and base react at molar ratios in the balanced reaction. That is where the moles of acid=moles of base if the reaction molar ratios are 1:1.

The reaction should change color at the equivalence point, but that will only happen if you have picked an indicator with the perfect pKa.
