Item# BSCHYD028G New calcium hydroxide in bulk. Food grade calcium hydroxide (hydrated lime) is used in Native American and Latin American cooking, and is called "cal". Corn cooked with cal becomes nixtamal which significantly increases its nutrition value, and is considered tastier and easier to digest. It's also used for pickling cucumbers the old-fashioned way for that extra crispness. Calcium hydroxide is a strong base, with poor water solubility. It’s often used to make lime water (a saturated calcium hydroxide solution) by mixing 1.85 grams in 1 liter of water. Molecular formula: Ca(OH)2 Water solubility: 0.185 g/100 ml pH: 12.4 for a saturated solution in water Melting point: 512 C (Decomposes into calcium oxide and water)
