Salamu Alaikum ahl al IslamicBoard!

I have a chemistry question that is driving me crazy. I have a table of data listing the change in polarisation (D) over time of a solution of sucrose in 4 molar hydrochloric acid (FINAL CONCENTRATION). This data needs to be manipulated in order to plot the Log (or alternatively Ln) of the amount of sucrose (the reactant) remaining vs. time.

And in order to calculate these values I need to take Log or Ln of the manipulated data.

Basically does anyone know how I can manipulate the data to get the amount of sucrose remaining in order to take Log of it???

Bro. You can use polarization values over time to see how polarization changed. That would indirectly give you amount of how sucrose's presence changed. There probably is a formula which relates polarization with sucrose concentration. Then you can take Ln or Log off the delta gradients. I hope that helped.

I think HCl is there to dissociate sucrose into glucose and fructose.

Unh! :exhausted Is that a trick question?...............

M shorry!:hmm: I wanted to help but don't know what this all unfamiliar, "a question from out of the world" is all about! Makes me +o(!........... Excuse me people, got to go!

Aha! SEE! Only Aliens could solve this unfamiliar so "out of the world question"! Brother mad_scientist (PAY ATTENTION TO THE NAME) is an.................ALIEN..................:nervous :
