Since there are 2 hydroxide ions (OH-) for every one molecule of Ca(OH)2, in 0.250 mol of Ca(OH)2 there are 0.500 mol of hydroxide ions. We can then multiply 0.500 mol by Avogadro's number to find the number of hydroxide ions present, which is approximately 3.01 x 10^23 ions.
Calcium hydroxide.
Calcium hydroxide is written as Ca(OH)2 because the hydroxide ion (OH-) is a polyatomic ion composed of one oxygen atom and one hydrogen atom. In the compound, there are two hydroxide ions associated with one calcium ion, which is why it is written as Ca(OH)2 and not CaOH2.
The products of the reaction between Na2CO3 (sodium carbonate) and Ca(OH)2 (calcium hydroxide) are NaOH (sodium hydroxide) and CaCO3 (calcium carbonate).
The molecular weight of Ca(OH)2 (calcium hydroxide) is approximately 74.09 g/mol.
The solubility in water of calcium hydroxide: 1,73 g/L at 20 0C.

Calcium Hydroxide, or CaOH2, is a base. Generally compounds containing hydroxyl groups and metals will act as bases in reaction.

Dis is King. 5.00 g CAOH^--First you want to balance this because its not balanced.CaOH2 x 1mol of CaOH2/Molar mass xGrams of Ca /1molCaOH=So itll be like this:CaOH2 x 1mil of CaOH2/74gCaOH x 40gofCA/1milCaOH= 2.70 G.
The solubility in water of calcium hydroxide: 1,73 g/L at 20 0C.

Calcium hydroxide formula is 'Ca(OH)2' Note the use of brackets, which indicate that there are two hydroxide anions in the formula. NNB CaOH2 is incorrect, because this indicates only two hydrogen atoms and one oxygen atom .
Bonds aren't strictly covalent or ionic - it's a whole grey area. CaOH2 probably has bonds with both covalent and ionic properties.
Laboratory preparation of ammonia or NH3 requires using ammonium chloride and calcium hydroxide. The reaction equation is 2NH4Cl plus CaOH2 gives the products 2NH3 plus CaCl2 plus 2H2O. The ammonium chloride and calcium hydroxide are heated for this reaction.
