Electrodeposition

If you think you know what metals look like, well, think again! During electrodeposition, metal cations in a solution get reduced at the electrode connected to the negative terminal of a power supply. This reduction generates Intriguing metal structures. Here, the electrodeposition of 5 different metals (copper, tin, zinc, lead, and silver) was recorded under a microscope.

Beauty of Science: Life-like precipitation

These life-like forms are the result of adding 0.1 M cobalt(II) chloride  to a 0.1 M solution of sodium hydroxide. The initial color of the precipitate was blue and purple; with time it changed to green and brown. This image consists of the results of three separate experiments, and is part of Envisioning Chemistry, a sequel to Beautiful Chemistry, which will be released Sept. 30.

Beauty of Science: K2Cr2O7

To make these crystals, the Beauty of Science team first made a saturated aqueous solution of potassium dichromate. Then they put a droplet of the solution on a glass slide. As the water evaporated, small crystals formed inside the droplet. The crystallization process was captured using time-lapse photography. Watch their video at www.beautyofscience.com/crystallization.
