and is created when Ca ions in hard water react with carbonate ions creating limescale. It is monly used medicinally as a calcium supplement or as an antacid but excessive consumption can be hazardous. Calcium carbonate shares the typical properties of other carbonates. Notably: it re...

What is the difference between baking soda and baking powder? Is bicarbonate good for the body? What does a high bicarbonate level mean? What is potassium carbonate? What is carbonic anhydrase? What is calcium dioxide? What acid is responsible for stomach acidity?
Good for: Limestone is calcium carbonate, which is generally white. Over millions of years, the skeletons from a constant rain of marine organisms, plus the chemical precipitation of yet more calcium carbonate build thick layers of sediment. Eventually, the heat and pressure of their own weight ...
What is Chalk Mineral Paint? Okay, so what’s the scoop on chalk mineral paint? Imagine a paint that’s like a smoothie for your furniture – full of good stuff! It’s got natural minerals like calcium carbonate (that’s a fancy way of saying chalk) and talc, mixed with water and ...
Then calcium carbonate from the decaying lime plaster might have been taken out by the roots of the trees growing there, uh, up into their leaves, and made them give off infrared light much more brightly than the surrounding vegetation. And infrared sensing technology can detect this. Student:...
What is the difference between soda ash and sodium bicarbonate? Who discovered sodium bicarbonate? What is sodium hydrogen carbonate? What is the pH level of sodium bicarbonate? What is the density of sodium bicarbonate? What is the chemical formula for calcium bicarbonate?
You’ve no doubt heard of talc filled polypropylene, but did you know that calcium carbonate is the number one mineral filler for plastics? There are quite a few options in the mineral family, and they not only reduce cost, they can also boost strength when added to a polymer. The shape...
Abalone shell is made of calcium carbonate. Abalone are named for the color or shape of their shells: red, green, black, pinto, white, pink, flat and so on. The iridescent inner lining is nacre which is also what pearls are made of. The lining is a colorful whorls and swirls the col...
light calcium carbonate is traditionally used for PVC pipes and profiles. In the past, due to the limitation of crushing equipment, heavy calcium carbonate could not reach this fineness. Now, the particle size of heavy calcium carbonate can fully meet the needs, even finer than light calcium ca...
