RIC - Single-Replacement Reaction

Formation of Silver Crystals: When a copper wire is placed in a solution of AgNO3, the Cu reduces Ag+ to metallic Ag. At the same time, Cu is oxidized to Cu2+. As the reaction progresses Ag crystals can be seen to form on the Cu wire and the solution becomes blue as a result of the formation of Cu2+ ions.

Deliquescence | chemistry | Britannica

The effectiveness of calcined calcium chloride in settling road dust is a result of its deliquescence. When spread in the form of a powder or flakes, it absorbs more than its own weight of water and forms a liquid that keeps the road wet. See also efflorescence.
