Dissolve chromium perchlorate hexahydrate (4.58 g) into 25 mL of purified water and shake vial thoroughly until all solid dissolves. In another vial, add 608 uL of ethylene diamine into 25 mL of purified water and shake the vial to mix. Add the ethylene diamine solution to the chromium solution. A precipitate will form upon addition. Shake the resulting solution on a platform mixer for 48 hrs. No precipitate should be visible. Any residual precipitate should be removed by centrifuging the solution and retaining the supernatant.
