# What is the formula of "ferric sulfate"?

Jun 23, 2016

#### Answer:

$\text{Ferric sulfate}$ has a formula of $F {e}_{2} {\left(S {O}_{4}\right)}_{3}$

#### Explanation:

How did I formulate this? Well, I have ferric ion, $F {e}^{3 +}$, and the sulfate ion, $S {O}_{4}^{2 -}$.

Clearly the salt is electrically neutral, so I take $2$ of the ferric ion, $\text{6 positive charges}$, and $3$ of the sulfate ion, $\text{6 negative charges}$.

Capisce?
