So it's measured in calcium carbonate, is the CaCO3 is the, is what you'd be looking at on the, on the test.

33:08Ross TretheweyPANELIST
That'll tell you how much calcium's in that water.

It looks like stone and, under the name of lime nitrogen or calstickstoff or nitrolym, is sold as a fertilizer.

74:04Adam MarceticNARRATOR
if it is desired to get ammonia it is treated with superheated steam the reaction produces heat and pressure so it is necessary to carry it on in stout autoclaves or enclosed kettles The cyanamide is completely and quickly converted into pure ammonia and calcium carbonate, which is the same as the limestone from which carbide was made.
A
74:32Adam MarceticNARRATOR
The reaction is CaCN2, calcium cyanamide, plus 3H2O, water, goes to CaCO3, calcium carbonate, plus 2NH3, ammonia.

Another electrical furnace method, the Serpak process, uses aluminum instead of calcium for the fixation of nitrogen, bauxite, or impure aluminum oxide.
A
75:06Adam MarceticNARRATOR
The ordinary mineral used in the manufacture of metallic aluminum is mixed with coal and heated in a revolving electrical furnace through which nitrogen is passing.

But I'd like to walk you through how, because I had the mechanism slightly wrong in my own head for a while, and the real version that I figured out a couple of years ago is really way more cool.

So agricultural lime is a calcium carbonate.
L
8:18Leonie SmithHOST
Its formula is CaCO3, so one calcium, one carbon, and three oxygens.

In WA, the main sources are limestone and dolomitic lime.

Now, the part that does the work is not the calcium and it's not the oxygen on its own.

before we talk about the kit we need to talk about the enemy because if you don't understand what water treatment is fixing you'll fit the wrong kit for the wrong reason and the customer will still have a problem the enemy is named precipitation not the rain kind the chemistry kind here's what you need to know water in a lot of the uk especially the south the midlands and parts of the east is what we call temporary hard water Temporary hard water contains calcium carbonate, chemical symbol CaCO3.

Most people just call it limestone because that is literally what it is.

Dissolved limestone carried in the water, invisible to the eye.
