H~~~ available a 1-1 beaker, an asbestos 10 N HC1, and a 40 X 40 crn sheet of aluminum foil cut into squares 5 cm on an edge.

and as the temperature of the system increases the reaction is dramatically accelerated as indicated by the increased CAUTION. DO not breathe the fumes from the reaction.

Demonstration

Remarks

Place the A1 squares in the beaker and add 50 ml of 10 N HC1. The exothermic reaction starts slowly,

The rate can be varied by changing the HC1 concentration.
