Im doing an assignment were im measuring the levels of CO2 and sugar in various different soft drinks. When i remove the sugar, do remove it from the soft drink with CO2 in it or do i use the soft drink with CO2 removed?
thanks

Are you allowed to just read it from the nutritional value on the side?

haha, i would do that, but im testin whether the nutritional value is right -_-

I dunno how you'd do the sugar bit. Perhaps distillation?

In both cases you weight the liquid and then remove the CO2 by shaking or stirring it. Then I'd boil it to get rid of the water. You'd be left with the sugar. Then weigh that.

Try reducing the syrup into a solid by heating it. I hope you're using normal soft drink, not diet or something like coke zero.

i did the solid thing but is that gna be accurate?
