Which of these is the formula for calcium hydroxide?

(a) CaOH
(b) Ca₂OH
(c) Ca(OH)₃
(d) Ca(OH)₂

Solution

(d) Ca(OH)₂
Calcium hydroxide comprises of calcium and hydroxide as the radicals. Since, the valency of calcium is 2 and hydroxide radical is 1, the formula of calcium hydroxide will be Ca(OH)₂ after interchanging their valencies.
