I am doing an experiment for science fair. I will like to know if 
lemon is more acidic than grapefruit and lime. I will do a 
titration and I will use Naocl and phenolthaleine as indicator. I 
know that the solution that takes more drop of the 
titulant(NaOcl)will be more acid. But this is not enough 
information. I know that it will be good use a ph meter but I 
don't have one. It is any other way that I could calculate the pH
at any time that put a drop of NaOCl in the acid before the 
equivalent point. I was thinking by using  the ml of NaOCl, but I 
am not quite sure.
