How to Test Chrome Plates With Copper Sulfate

Put on gloves, protective eye wear and an apron.

Place 8 grams of copper sulfate into the glass container.

Add 500 milliliters of distilled water to the copper sulfate and mix carefully.

Add 2 milliliters of sulfuric acid to the copper sulfate and water solution. Let the components dissolve fully.

Test small objects by immersing them in the copper sulfate solution; larger objects require spot testing. Use a stiff paint brush to apply the solution to a small area of the large object. Leave the object in the solution or on the test area for 6 minutes.

Rinse the object with water to clean. Scrub the object with a small brush to ensure removal of the copper sulfate solution.
