    Bio/chem relation between pH and [H+]

    Hi my question is How does the pH relate to the concentration of Hydrogen ions? what I think is The relationship between the pH and the concentration of Hydrogen ions is that the -log of the hydrogen ion concentration is equal to the pH, but this doesn't seem right at all. can someone...

    Diethylene glycol in WINE question help please CHEMISTRY gr 12

    http://en.wikipedia.org/wiki/Fractional_distillation using the apparatus in this link the round flask would have the wine and then i would heat it to the boiling point of the diethylene glycol? then what would vaporize into the other flask? Would one flask have purified wine and the other the...

    Diethylene glycol in WINE question help please CHEMISTRY gr 12

    Distillation is probably the way to go but I don't know how to do this using boiling points. This looks like the right way to do it because I was reading stuff about alcohols, aldehydes, ethers, ketones, naming these and then their would be a property section where it would talk about boiling...
