Hi All,
    I was wondering what everyone uses to make alcohol dilution's.  At our 
lab for as long as I can remember, we made our dilution's with distilled 
water.  Now we are just using tap water.  I personally do not believe this is 
the correct way, however, I have been wrong before.  By dilution's, I am 
referring to percents (100%, 90%,80%, etc.).  Thank you for any assistance.
