    Isopropyl alcohol for titration?

    Does anyone know where I would find reasonably-priced isopropyl alcohol for titration?

    Back home (Canada), every drugstore had rubbing alcohol for like $3.00 a bottle. I went to a pharmacy here and their "rubbing alcohol" was 2% methylated spirits.

    Finally, I went to Bunnings and got 100% isopropyl alcohol, but it was $11 for 125mL

    Just use ethanol (methylated spirits) if you have liquid oils. Works fine for the titration.

    Will that work for oils that are solid at room temperature as well?

    It will. For solid fats you are going to have to heat them up first so you can ensure they are throughly mixed before drawing the sample.

    Then when actually doing the titration if the oil starts to go solid again bung it in the microwave. But only nuke it until you see the very first signs of any bubbling. It won't take much.
