Write the net chemical equation for the chemical reation between HNO3 and Ca(OH)2

This is what I did... can some one please tell me if I did this correct... thanks!
Ca(OH)2 + 2HNO3-> Ca(NO3)2 + 2H20
Ca2+ + 2OH- + 2H+ + 2 NO3- --> Ca2+ + 2NO3- + 2H20
2OH- +2H+ --> 2H20

Also when is titration complete?  Is it when all the H+ ions in the orginal solution have reacted with an equivalent number of OH- ions added to the solution known as the equivalence or end point, and one can see this by the change of color of the solution by the indicator??

Equations are OK (although canceling 2 in the last one won't hurt ). As to the second question - end point and equivalence point are two different things. Equivalence is when all reacted, end is when you THINK (using some detector) that they all reacted.
