Precipitate Comparison Test; Borax and Sea Salt with Calcium Silicate

I perform a quick precipitate comparison between borax and sea salt with calcium silicate. The difference is startling to say the least.

I note that much of the precipitate has got to be the eroded material from one of the plates. This can only mean that there is a high concentration of Chromium in the sea salt sample and a simple 1/4 teaspoon of ferrous sulfate will not be enough to reduce the Cr(VI) to Cr(III).

Well since you're trying different electrolytes, was wondering if you could test magnesium oxide. or better known as antacid. There are 2 reasons why I suggest it, one it becomes highly conductive in water, separating hydrogen and oxygen atoms easily. second just by heat it will release hydrr. therefore. in electrolysis should produce a lot of hho.
