Calcium Hydroxide Electrolyte After Test Observations

I make some after test observations of using Calcium Hydroxide as an electrolyte. I lost a clip that showed the particulate settling, but the action was so slow I would have needed to speed it up somehow.





My After Test Observations

1. Calcium Hydroxide leaves hard water deposits on the glass surfaces. I'm sure it would apply to plastic or stainless steel as well.

2. The electrolyte leaves a hard deposit raft on the surface if left for a few days. This may be because it was a saturated solution. The weaker solution in the second test will provide some insight into this phenomenon.

3. The particulate settles out like watching the mass self compress leaving almost clear water above it. Most other compounds settle out like watching a blizzard that tapers off.

Adjusted Concentration for Calcium Hydroxide Electrolyte Test

I conduct a second test using Calcium Hydroxide as the electrolyte. The concentration this time was 1/4 teaspoon per gallon.




My Observations

1. The gas production is moderate at best.

2. there are very low levels of particulate when compared to 1 teaspoon per gallon.

3. The amperage is very low indicating the electrolyte could be in stronger concentration, but the cost of doing so may be to filter out the white particulate before use.

4. There is a considerable amount of scum that forms at this concentration. It may dissipate over time, but did not do so in the hour and 45 minutes I ran the test.

Adjusting the Recipe for Reducing Hexevalent Chromium in Vinegar

I take the time to adjust the recipe for reducing hexevalent chromium in vinegar and record the results.



My Observations

1. It takes quite a bit more calcium hydroxide to cause seperation of the particulates. 6-6 1/2 Tablespoons versus 1/2 Tablespoon.

Saturation Test with Calcium Hydroxide in purified water

I conducted a water saturation test with calcium hydroxide (lime) in purified water and observed the results.




My Observations

1. Calcium Hydroxide resists going into solution.

2. To get the desired concentration, the water has to be heated or allowed to stand before filtering the undissolved portion of the calcium hydroxide.

Electrolysis Test with Calcium Hydroxide

I conduct an electroysis test with calcium hydroxide (lime) in reverse osmosis purified water.




My Observations

1. Calcium Hydroxide does not readily disolve in water.

2. The one tablespoon per gallon used creates a lot of white precipitate.

3. Heating or standing may allow more to dissolve.

4. Remaining precipitate should be filtered before using

5. Foam forms near the beginning of the test but dissipates between 40 and 60 minutes into the test.

6. Brown particulate forms in considerable quantities and forms larger flakes than other tests.

7. Good gas production is observed.

Hexavalent Chormium Initial Test

I conducted an observational test of adding ferrous sulfate and calcium hydroxide (lime) to my water samples in order to reduce the Hexavalent Chromium, Cr(VI) to Trivalent Chromium, Cr(III).




My Observations

1. The sludge forms as predicted in the research in three of the four tests.

2. The failed test involved vinegar in 5% concentration. I anticipate the acidity of the water affected the formation of sludge, so the next test will adjust the amount of lime in an attempt to neutralize the acid.
