(I failed chemistry miserably...)
1. What's the difference between a -drate and a -dride?
2. What's the difference between chlorohydrate and hydrochloride? |

-drate has oxygen in it, -dride doesn't.
Example:
Sulfate is SO4 (2-)
Sulfide is just S 2-
I will asnwer the other bit when my friend answers me...hehehe |

The only hard and fast rule is that "ate" is a higher oxidation state than
"ite," which is a higher oxidation state than "ide." Sometimes you need
additional prefizes to fill the whole spectrum. The classic example is the
halogens, take for instance chlorine.
Cl- chloride
ClO- hypochlorite
ClO2- chlorite
ClO3- chlorate
ClO4- perchlorate

I think the only hard and fast rule in chemistry is to wait until Mr. Peebler is looking the other direction and ask JoEllen Schmidt for the answer. She was FAR more likely to know the answer than Art Bedford who was always busy heating up pennies in the bunsen burner. |
