A 10 cm by 10 cm piece of graphite has the
face area of 100 square cm mentioned in this ex-
ample. A 1000 ml to 2000 ml beaker or similar
size plastic measuring cup or pitcher are suitable
for doing the plating in. If the 350 ml of plating
solution doesn't fill up the container enough to
completely submerge the graphite to the extent
shown in the drawing, switch to a different con-
tainer, or dilute the plating solution with water or
dilute HC1.
