charge balance question

Post by merrittr »

I am taking a GeoChemistry class and havent taked chemistry since first year so I have this question. What we are asked to do is calculate charge balance

so (mg/L)/GFW * valence

and for SO4 (-2) i listed

but for Ca no valence is listed is Ca +1 or as I think +2?
