Sodium, potassium, calcium.

Potassium and magnesium.

It's not different, it's the same stuff calcium carbonate, calcium carbonate.

Oh, then sodium carbonate

And they said, calcium carbonate.

There's consequences for carbonate organisms.

And he had potassium nitrate.

Bananas are an excellent source of potassium.

Well, no, the potassium hydroxide is the electrolyte.

They can pull calcium out of the environment, and put down a layer of calcium and then carbonate, calcium and carbonate.

The main framework material of coral reefs is calcium carbonate.

But it's not just the carbonate producers that are affected.

like calcium, potassium and magnesium from out of desalination brine.

And I said, that's what this is this is calcium carbonate.

And these are individual potassium ions that are flowing through that pore.

When you evaporate seawater, the first thing to crystallize out is calcium carbonate.

I said, what kind of salts of potassium do you have? You know.

Oh, by the way, just in case you weren't already guessing, it's calcium carbonate.

It had three chemicals we were really surprised to see sulfur, potassium nitrate and charcoal.

There are many organisms that build their shells out of calcium carbonate plants and animals both.

If there is too much uranium or potassium or thorium, probably, again, there would be no life.

Here, we've got a protocell to extract carbon dioxide out of the atmosphere and turn it into carbonate.

And we know very well that geothermal energy is mostly produced by decay of uranium, thorium, and potassium.

Acid rain from cities and industries leeches the soil of vital nutrients, such as potassium, calcium, and magnesium.

This abalone shell is a biocomposite material that's 98 percent by mass calcium carbonate and two percent by mass protein.

We can analyze the carbonate that makes up the coral, and there's a whole bunch of things we can do.

Iridium layer at the K T boundary, and potassium argon dated crater in Yucatan, indicate that an asteroid killed the dinosaurs.

Because the lowly abalone is able to lay down the calcium carbonate crystals in layers, making this beautiful, iridescent mother of pearl.

And that builds up on the evaporators and that's what that image on the left is gradually getting encrusted with the calcium carbonate.

They send it out for amateur rocketeers, and it said in there do not ever heat a mixture of potassium perchlorate and sugar.

Aluminum buffer action, aluminum hydroxide is what we think it is, uh, plus the barium carbonate, strontium titanate, strontium oxides, barium oxides, probably some aluminum oxides in there.

So, I went to the drug store and I tried to buy some potassium perchlorate and it wasn't unreasonable then for a kid to walk into a drug store and buy chemicals.

You know, I started off with little tiny amounts of potassium nitrate and sugar, which was readily available, and I mixed it in different proportions, and I tried to light it on fire.

You sort of now you say, well, let's see if I can get hold of some potassium chlorate and sugar, perchlorate and sugar, and heat it it would be interesting to see what it is they don't want me to do, and what it is going to and how is it going to work.

If you want to be able to manipulate the weather, one of the things we know about the materials that are being used in the aerosols we we've seen everything from aluminum oxide, barium salts, strontium, copper sulfate, uh, potassium iodide, um, a number of different kinds of things, each of which have different levels of reactivity with the moisture in the air.
