What is the formula for calcium hydroxide and how is it classified?
A) CaOH, a weak base
B) Ca(OH) 2, a weak base
C) CaOH, a strong base
D) Ca(OH) 2, a strong base
Calcium Hydroxide
A white crystalline compound with the formula Ca(OH)2, often used in the production of cement, plaster, and in water treatment.
Strong Base
A strong base is a substance that can completely dissociate into its ions in aqueous solution, resulting in a high pH.
Weak Base
A base that does not fully dissociate in solution, resulting in a relatively low pH compared to strong bases.
