Red Cat | Oil Rig

Short answer: When copper metal is placed in silver nitrate solution, copper atoms lose electrons and enter solution as copper(II) ions, turning it blue, while silver ions gain electrons and deposit as solid silver crystals. It is a single-displacement redox reaction.

The title combines two mnemonics: "red cat" (reduction at the cathode) and "OIL RIG" (oxidation is loss, reduction is gain). The footage shows silver crystals growing on a copper coil.

Video transcript: Red Cat | Oil Rig: Copper Wire in Silver Nitrate Grows a Coat of Silver Crystals

Did you know, in the reduction oxidation or redox reaction between copper and silver nitrate, copper metal reacts with silver nitrate solution to produce copper II nitrate and solid silver. Copper loses electrons and is oxidized to form copper II plus ions, while silver ions in the silver nitrate are reduced, as they gain electrons to form solid silver. This reaction showcases a single displacement where copper displaces silver from the solution. NOW YOU KNOW!
