Hello all,
While reading another post I was reminded of a chemistry question that popped into my head a while back.
I sometimes think about supplementing my MSU-formula fertilizer regime with calcium nitrate and magnesium sulfate. But if I mix the two in the same watering, solubility rules say that calcium sulfate will precipitate. So why doesn't a precipitate form in fertilizer solutions that contain both calcium nitrate and magnesium sulfate? Is there some form of the chemicals that won't lead to precipitation?
And on a barely related note, which chemical is it that turns fertilizers blue-green? I bought 5 pounds of a MSU mix which was whitish until I left it open to the air and the top layer turned blue-green. Is there a hydrate that's white when anhydrous and blue-green when saturated?
My extensive chemistry experience of a single chem 101 class can't answer these questions. Any help would be appreciated.
