Abstract. A microwave
oven is used for the gravimetric analysis of several transition metal
complexes, in particular, the dehydration of Fe, Ni, Co, Cu and Zn aqua
complexes. This is a simple, convenient, and colorful experiment using
transition metal aqua complexes. The procedure is designed to help chemistry
students understand the concept of coordinated water.
