Q

what does pipette mean?

A

17
Q

what does titrant mean?

A

the standard solution in a burette that is added to a solution of unknown solution

18
Q

What’s the difference between end point and equivalence point?

A

the equivalence point of titration is reached when chemicals have reached according to the molar ration with no reactant in excess.

the end point is when the indicator changes colour
it is important that the indicator changes colour as close as possible to the equivalence point.

19
Q

what is the purpose of the titration curve?

A

A titration curve is a graph of the pH as a function of the amount of titrant (acid or base) added.
