when heating a beaker, where should the burner flame be located for maximum heating?

  • Chemistry -

    middle of the beaker I assume.

  • Chemistry -

    Under the middle of the beaker.

  • Chemistry -

    Under the beaker with the tip of the inner blue cone of the burner just touching. However, I never like to heat a beaker directly (unless it's made of Vycor). I prefer to place the beaker on top of a wire gauze and heat the wire gauze. Beakers made of Pyrex have been known to crack if heated directly.
