Chemistry Question - Distillation - Why tilt the condenser?

  1. Nov 11, 2008 #1
    1. The problem statement, all variables and given/known data

    Give two reasons why the cooling water is led into the lower end rather than the upper end of the condenser?

    2. Relevant equations

    We were distilling a Cobalt III solution.

    3. The attempt at a solution

    I think one reason may be to prevent air pockets forming in the top corner, which would lead to cracking the glass. But another reason for it escapes me. I've been referred to the "Countercurrent" theory, but I fail to understand it. Please help.

    Thank you in advance, I appreciate any guidance you can give me. (:

    Welcome to the Forums!

    Think about heat exchange and the temperature of the fluids on either side as you move from top to bottom (or vice versa).

    Maybe you need to search "counterflow heat exchanger" rather than countercurrent theory.
