The basic chemical process used to make the material has not changed since it was discovered in 1888. When any grade of calcium carbide comes into contact with water, a chemical reaction immediately begins, which yields two new compounds, one of which is acetylene, a very useful flammable ...
Is calcium carbonate a base? What is the pH level of sodium bicarbonate? Is sodium bicarbonate dangerous? What is a sodium bicarbonate IV used for? Is sodium bicarbonate a metal or nonmetal? What type of compound is sodium bicarbonate?
Calcium makes such an effective antacid not only because the form it most often appears in, calcium carbonate, is highly basic/alkaline (the opposite of acidic), but also because it works longer than almost any other antacid, giving it an impressive neutralizing capacity. This is also the ...
If you were pressed to explain why the CaCl2 solution would be "slightly basic" then you can "rationalize it" I suppose by the fact that for every one calcium ion that is released you release two chloride ions. These chloride ions are VERY weakly basic and so they can liberate OH- ions...
It could be silenced ___29___ shellfish have been struggling to build their calcium carbonate (碳酸钙) shells, which is a result of ocean acidification. Even worse is the possibility ___30___ we will have no seafood to enjoy at all. In a 2006 Dalhousie University study, s...
the calcium carbonate crystals form ridges.During the following day (when the coral polyp is retracted and lying on its new structure), the valleys between the ridges fill in with more calcium carbonate and the skeleton takes on a smoother appearance.Because the skeleton of hard corals is made...
What are examples of acidic and basic salts? Identify and define the two forms of acid rain. What is common to all acids? What are seven strong acids? What is the chemical name for water? Rank the following compounds from strongest to weakest acid. ...
