JennyHale-2+n-octanoic+acid+problem

 * [Jenny - Good job in getting to the bottom of this and fixing it. But this really belongs on the page of the original experiment - in the discussion section (an experiment can't have more than one page). Everyone following this wiki will see your update there because they are likely subscribed to the entire space (under the notify-me tab). You should update your spreadsheet and the master solubilitysum sheet accordingly JCB]**

I have started a separate page for this as I want to add pictures and I felt it warranted a separate page so everyone could see my write up.

Khalid had contacted Jean-Claude to query a result of mine and I was contacted about it. The problem was that I had reported n-octanoic acid to be a white solid when it melts at 17°C. Obviously our lab is not likely to be so cold that it is still solid, as later experiments have measured the room temperaure of the lab to be 23°C. I have been back and found the mistake is mine. On the spreadsheet for the experiment, I have written that n-octanoic acid is also known by the name caprylic acid. On the experimental write up page, I only wrote the IUPAC name. I have been back and retrieved the pot of caprylic acid. In smaller writing underneath, it says sodium salt. I had not noticed this when I picked up the pot initially and carried out the experiment. This was extremely careless of me and does make a case for always photographing the chemical. Here are pictures of the label on the pot and a sample of the contents:

I will check what details I have written down for the compound in the spreadsheet and amend accordingly if I have the RMM for n-octanoic acid written down.

Sorry for the confusion, and thanks to Khalid for flagging up my mistake.
