Calcium hydroxide is a solid at room temperature. It becomes a liquid when heated above 1000 K. The melting point of calcium hydroxide is more than 3000 K.
A compound is a mixture of elements. As the name implies, CH (or calcium hydroxide) is made up of calcium and hydrogen. Calcium and Hydrogen are elements. Thus, calcium hydroxide is a compound.
The chemical formula of Calcium hydroxide is Ca(OH)2
Calcium and hydroxide ions combine in a 1:2 ratio, where one calcium ion (Ca^2+) combines with two hydroxide ions (OH^-) to form calcium hydroxide (Ca(OH)2).
Calcium hydroxide is basic and hence the litmus will remain blue.
As calcium forms the 2+ ion, and hydroxide has a negative charge, the formula would be Ca(OH)2
solid
Anytime you have a reaction that changes the state of the matter, such as the change from calcium oxide to calcium hydroxide, it is a chemical reaction. Ex. CaO+H2 reacts to form CaOH you then must balance the charges by putting a 2 in front of CaO and CaOH 2CaOH + H2 reacts to form 2CaOH
i didnt ask what calcium is
Calcium is a solid metal.
to get calcium hydroxide: Quicklime (calcium oxide) + water = slaked lime (calcium hydroxide) the calcium oxide has a chemical reaction with water to get the calcium hydroxide hope this helps :)
Calcium is the metal present in calcium hydroxide..
Yep, everything with 'hydroxide' can be called an alkali no matter its state of matter. :)
Calcium hydroxide is not en element it is a compound.
Calcium Hydroxide
Calcium hydroxide is not en element it is a compound.
Calcium hydroxide is an ionic compound. It is made up of a calcium ion (Ca2+) and two hydroxide ions (OH-), which are held together by ionic bonds resulting from the transfer of electrons from calcium to hydroxide.
