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).

After Electrolysis Observations; Sea Salt & Calcium Silicate

I make some significant observations regarding sea salt and calcium silicate.





My Observations

1. The amount of particulate is extreme and has a dark almost black appearance.

2. CLR does NOT cleanup the plates worth a darn.

3. The Positive(?) plate is eroded pretty badly. The erosion is most notable along the plate edges and pitting pretty bad on the side of the plate facing the negative plate.

4. The gunk even blackens the CLR.

5. The temperature electrode was pitted as well.

6. I suspect if there ever was a candidate for Cr(VI) or Hexavalent Chromium reduction, this sample is it. The mere evidence of erosion of one of the plates is proof enough that there is significant chromium in the particulate.

Observational Electrolysis Test Using Sea Salt

I conduct a observational electrolysis test using sea salt with calcium silicate(yes, that's what the box states is in it) and observe the results.

I don't recommend anyone duplicating this test because Chlorine gas can be produced by the test.



My Observations

1. Good gas production is observed.

2. Holy cow! enough particulate to clog a landfill! Now if that ain't a bucket of mud I don't know what is!

3. Needless to say there's no need to recommend San Fransisco Bay Sea Salt as an electrolyte!
