Vitamin C content

[Bee =3]

I'm designing a practical experiment on the Vitamin C content of commercial tablets. But I need to formulate the research question in such a way that it is an investigation, not a simple quantitative "determine vitamin C content of..".

I'm guessing, it'll have to be some kind of research into how the content varies with something. But what could be that something? Or any other suggestions?

HMM..

thanks!

Suggestions, yes but "what could be that something" no, lol.

For example:

Determining the rate of amylase enzyme activity at pH 2, could be put as: What effect does a low pH of 2 could have on the rate of amylase activity?

With commercial tablets, I guess it varies depending on, well, the concentration of vitamin C the manufacturer chooses to put in it - pretty straightforward.

I did a similar experiment for my group 4 presentation, where me and my group looked at differently-coloured bell peppers and determined the vitamin C concentration of each, to find the correlation between colour and vitamin C concentration.
