If you titrated vinegar into standard NaOH & distilled water, how would you recognize the endpoint?

Answer 1

Hi,

The standard method is to add phenophtalein to the solution, and when the endpoint is reached, the solution will change color.

Hope that helps,
Matt

Answer 2

Use a ph meter and plot the graph of pH vs volume, or use the millivolt readout. The change of inflection of the curve plotted is the endpoint. Graph should be a "s" shape.
