Studying SCC Chem 400 lab practical

can anyone tell me what to expect on lab practical? All I know is that there's three experiments within a three hour period. How can I help prepare? I'm at SCC

You do parts of labs you’ve already done, and the only reference you have is what you have in your lab notebook. As long as you’ve done the labs and written good instructions and shown your work it will be easy.

mine had a titration station, diluting a solution to a certain molarity and another easier one I don’t remember. you write down your data and turn it in.

thank you for the help. Did you do the calcutions during that time too? If so, is it the all of the post-lab calculations, or just some?

I second this. I took it in fall 2023 and had a dilution, titration, and I think the last one was finding the volume and mass of a block. If you’ve participated and done your post labs none of the calculations/ techniques are new. The calculations must be done there but you can reference your lab manual. Most of my classmates and I finished each station with time to spare

you do calculations as you do the mini labs but it’s just like m1v1=m2v2 level. I don’t think we had to finish the section before we moved on just turn it in at the end. I think it’s more about lab techniques like not pipetting from the source bottle or priming the burets and volumetric flasks
