Why is it ca Oh 2 and not CaO2H2?
Ca(OH)2 cannot be written as CaO2H2 this is because calcium hydroxide constitutes of calcium ions and hydroxyl ions and not oxygen and hydrogen ions.
What is CaO2H2?
Tool Overview: Molar Mass of Calcium hydroxide (CaO2H2)
Is Ca Oh 2 the same as CaO2H2?
The formulas CaOH2 and Ca(OH)2 do not describe the same compound. In the case of CaOH2, there are one calcium atom, one oxygen atom, and two hydrogen atoms, since there is a two attached to the H of the formula. In the case of Ca(OH)2, there are one calcium atom, two oxygens atoms, and two hydrogen atoms.
Why do we write Ca Oh 2?
Ca(OH)2 is an ionic compound, in which Ca is the cation and OH is the anion. Ca (calcium) has a charge of 2+, since it is in group 2 on the periodic table. OH (hydroxide) is a polyatomic ion with a charge of -1.
What is the cation of Koh?
In potassium hydroxide, the cation is potassium while the anion is hydroxide.
Why is caoh2 not CAOH?
Ca(OH)2 is a base because on dissolving in an aqueous solution, it dissociates into two ions(Ca2+ and 2OH–), the presence of OH– ions in the aqueous solution of Ca(OH)2 makes it basic in nature.
