Sorry, as I was quite unclear with what I was asking and with my question.
Basically, I did a lab on mixing lemon juice/slice with water, and I observed the results for three days.
I have used vitamin C test strips, not the iodine titration method.
And I meant correct by if it is suitable to my topic. For instance, the first equation is used for iodine titration people say, and the second one does not show water in it, so I assume that it's wrong.
So, if I take out iodine from the first equation and balance it, which would be C6H8O6 +H2O => 2H^+
Is this equation correct and is it suitable for my topic?
