Question

How would I write an ionic equation to show the formation of ions from sulfur, calcium and arsenic?

Answer 1

Well we would assign oxidation states of...`S(-II), Ca(+II), As(-III)` respectively....

Explanation:

And so formally we could write....

`S+2e^(-) rarr S^(2-)`

`Ca rarr Ca^(2+) + 2e^(-)`

`As+3e^(-) rarr As^(3-)`

Of course these are individual redox reactions...
