Crystallography

Crystallography is the category of science that focuses on the atomic and molecular arrangements with their bonding constituting the crystal structure. It is derived experimentally and originated in the year 1912. It is a combination of two words; those are crystal, meaning a cold drop, and graph, meaning writing.

Can the Nernst equation be used at temperatures other than room temperature?
Coprecipitation due to surface adsorption can be minimized by the following except: reducing the surface area, i.e precipitating under conditions where more nuclei are formed and small crystals resulted Carrying out a separation of ions that would be strongly adsorbed or replacing it with strongly absorbed ions lowering the oxidation number of metal ions so that it's charge reduced using hot solutions to reduce the amount of adsorption per unit area
