Surface tension of water+alcohol

  1. Jan 15, 2013 #1
    1. The problem statement, all variables and given/known data
    explain the change in surface tension of mixture of water+alcohol(n-octanol,n-heptanol,n-butanol)? discuss their degree of their solubility in water and this affect to surface tension?


    2. Relevant equations
    L=SURFACE CONCENTRATION
    δ=SURFACE TENSSION
    C=CONCENTRATION OF ALCOHOL IN WATER
    L=(1/RT)*∂δ/∂ln(c)
    3. The attempt at a solution
    If a alcohol is soluble a little in water it can change surface tension so much if a little amount of alcohol is added.
