# What is the formula for calcium acetate?

Apr 17, 2018

${C}_{4} {H}_{6} C a {O}_{4}$ or $C a {\left(C {H}_{3} C O O\right)}_{2}$

#### Explanation:

In here, calcium is the cation, and has a charge of $2 +$, while the acetate anion contains a charge of $1 -$, and so two acetate ions balance out one calcium ion.

And so, the formula would be

$C a {\left(O A c\right)}_{2}$

Acetate ion has the chemical formula of $C {H}_{3} C O {O}^{-}$.

And so, we get:

$C a {\left(C {H}_{3} C O O\right)}_{2}$

We can either keep it like this or simplify it.

If we want to simplify it, it becomes:

$C a {\left({C}_{2} {H}_{3} {O}_{2}\right)}_{2}$

$C a {C}_{4} {H}_{6} {O}_{4}$

And then, we can rewrite it into:

${C}_{4} {H}_{6} C a {O}_{4}$
