Hey guys! I have a question that has been bouncing around on my mind for quite a while now. You guys may have guessed what it is by reading the Topic Title of this post, but if you missed it, what, in your opinion, is the MOST unhealthhiest food of ALL TIME? My friend told me that lasagna is the most unhealthy. Is this true? Also, are Vegi-Chips healthy as they are made out of vegetables? Happy discussions! Peace fofo.
Cutie Cat posted a file in Pre-IB/MYPTests the effect of adding NH4Cl (a salt) to various liquids, such as distilled water and acetic acid, on the temperature change of these liquids. This is a full lab report including an objective, variables table, hypothesis, materials, procedures, qualitative and quantitative data, sample calculations, graph, conclusion, further investigation topics, and works cited. The lab was written for a 10th grade (year 11) Pre-IB chemistry course and received a 97%. The course was taught by the same teacher that teaches IB Chemistry SL and HL 1.
Emilia1320 posted a topic in ChemistrySo, is there any drawbacks on using distillation on aqueous solution containing a low concentration of salts of cadmium so that it would be easier to detect cadmium on solution as concentration would increase? When I distillate it would it be so that all of cadmiumic salt would stay on the original container and only water evaporate away? So for the concentration of cadmiumic salt would be for example 10 times larger if I distillate 9/10 of water away? I can't figure out any drawbacks but I guess there is some... So I would find it awesomely helpful if someone could give me some feedback on usage of method like this
