<p>Two common tests to identify the presence of water vapor are the anhydrous copper sulfate test and the cobalt chloride test. In the anhydrous copper sulfate test, the presence of water vapor causes anhydrous white copper sulfate powder to turn into blue crystals of copper sulfate pentahydrate. In the cobalt chloride test, dry blue cobalt chloride turns pink when it comes in contact with water vapor, indicating the presence of water vapor.</p> Signup and view all the answers
