Properties of Capacitors of differing types.

In circuits and electronics they told us that a capacitors are defined by capacitance in farads and breakdown voltage. But in the real world there are many different types of capacitors: ceramic disk, Tantulum, polarized electrolytic, non-polarized electrolytic. I originally thought that the capacitance required dictated the technology used, but I've noticed there is significant overlap between different types.

What I want to know is are capacitors of different types with equivalent measurements electrically identical or not? If they are not, then how do I know what type is needed from a schematic? The reason I am asking is I am fixing a board that looks like it has some bad 1uF 50 volt polarized electrolytic, my local Radio Shack only has Tantulum and non-polarized electrolytic with those specs. Can I substitute?
