AI Thread Summary
The discussion revolves around an experiment on the conductivity of solutions, specifically focusing on how to calculate molar conductivity from given results, which include acid concentration in mol/dm and conductance in mS. Participants seek clarification on deriving the molar conductivity and the relationship between acid concentration and conductance. The conversation also touches on Kohlrausch's law, questioning whether Mandelic acid and HCl follow this law and their classification as strong or weak acids, with HCl confirmed as a strong acid. Additionally, there is a request for the literature value of HCl. The experiment is part of a physical chemistry lab course, and some participants express a willingness to assist further, although they note the need for more detailed information about the experimental results.

Hi everyone :)

please I need help to show me what to do with these points related to the conductivity of solutions experiment :

1- results I got from this experiment are the acid in mol dm and the conductance in mS.

however, how can I get the aci in mol m,square root of the acid in mol/dm and the molar conductivity?

2- In Kohlrausch's law, do Mandelic acid and HCL obey the equation and are they strong or weak acids?

3- What's the literature value of HCL?

Thanks

what course is this for?
 
it's for chemlab (physical chem.) experiments...
 
I've not taken physical chem before...here's a link, hopefully it'll refresh your memory. Otherwise, chemtr or someone else should be able to help you out.

By the way HCl is a strong acid. The experiment seems simple enough, I may be able to assist you with the problem, yet I don't have the complete info on this subject with me at this time. You can try explaining it more extensively. Also it seems that some of the questions actually depend upon your experimental results, you should discuss these also.

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
