sorry misread i think the limewater milky will do

just remembered they always like to throw a respiration test with soda lime. Something i didnt know is that the more oxygen present, the more alkali. So if the question were to have a plant and an animal in seperate test tubes and it asks which are acid or alkali always say the plant test tube has alkali gas and the animal acid. CO2 is acidic

Awesome thanks! Yeah, luckily it's an afternoon one. Also transpiration sometimes comes up, then the old easy stuff - drawing, labelling, graphs, etc

Yeah, I've seen it on a couple past papers. Quite simple, but just a little side not :smile:
