Solution
The correct option is B False
The given compound has two parts. One is Calcium ion and the other is Hydroxide ion. Calcium ion is Ca2+ and Hydroxide ion is OH−. By using the criss-cross method, we can get the formula as Ca(OH)2. 'OH' should be in the parenthesis because the '-1' charge is not just on 'H' but on 'OH'.
