(b) Preparing the Apparatus.—Provide any suitable means for con-necting the copper sheets to the wires of an electric circuit. Shake upabout 200 grams of crystals of copper nitrate with about 50 of wateruntil a saturated solution is obtained. Dilute 50 of this solution with SCHOCH! IXTEODUCTOEY Chemistey. ^WWWWWA Rheostat
