Introduction: Make Manganese Sulfate From Manganese Dioxide (2 Ways)

How to Make Manganese Sulfate from Manganese Dioxide. We'll show two ways on how to do this. One using sulfuric acid and oxalic acid, and another using sulfur dioxide.

First the manganese dioxide must be thoroughly washed and filtered to remove all soluble contaminants like zinc chloride and ammonium chloride.

In the first method 30grams of oxalic acid, 300mL of water, and 13mL of sulfuric acid are mixed together. Then the manganese dioxide is continually added until the solution stops bubbling.

In the second method. The manganese dioxide is mixed with water and an excess of sulfur dioxide is bubbled through. The reaction produces manganese dioxide directly.

Finally, after both methods. The mixture is filtered to give pink manganese sulfate.

Interesting video however if you want pure Manganese sulfate or Mangese dioxide you should look on Prolab (Canadian Only) and e-bay.

I had that same torch but i lost it, which reminds me, i gotta get a new one!

I was unsure what was happening when I did a similar experiment using a large NeoD magnet and a bowl of water. I placed the magnet in a bowl of water and reflected a pocket laser flashlight on the surface which allowed me to plot the reflected curvature of the surface due to the magnetic influence. I was unsure if this was due to repulsion or density alignment compression. I have not worked out how to test for density alignment compression but reasoned that it should affect the refractive index of the water. I understand the fact that the water is repelled, thank you for that. It is the hydrogen that is being repelled I think. I do enjoy your video.
      Thank you.

Did you buy the sulfur candle or make it yourself? And if so, how?
