Most of the times the silver ion is reduced, but sometimes the nitrate ion is reduced. It reacts with copper to make silver crystals and copper(II) nitrate. It turns into silver, nitrogen dioxide, and oxygen when it is heated. It is the least expensive silver compound. It reacts with bases to make dark brown silver(I) oxide.


It is made by dissolving silver in nitric acid. This produces nitrogen dioxide, so it should be done where the person can get fresh air.
