Calcium Hydroxide/Hydrated Lime
CAS No. 1305-62-0
EINECS No.:215-173-3
Formula: Ca(OH)2
Property
Calcium hydroxide, traditionally called slaked lime, is an inorganic compound with the chemical formula Ca(OH)2.It is a colorless crystal or white powder.
Calcium hydroxide is a strong base. Calcium hydroxide of alkaline stronger than sodium hydroxide, but because the solubility of calcium hydroxide is much smaller than the sodium hydroxide, calcium hydroxide solution so corrosive and alkaline smaller than the sodium hydroxide.
These properties determine the calcium hydroxide has a wide range of applications.
