Jan 26 2016 · Purpose To determine the solubility of calcium hydroxide (lime) Background What is limewater When Calcium reacts with water it produces Calcium Hydroxide commonly known as lime. This lime is solid but dissolves slightly into aqueous calcium and hydroxide ions a solution known as limewater. This is represented in the following equation Ca(s) H2O → Ca(OH)2(s) ↔

May 15 2017 · Thereby it was observed that Al-doped pellets retain their shape for one reaction cycle. Pure and doped pellets decomposed after repeated cycling resulting in a fine grained powder with a strong agglomeration tendency. Similar results upon aluminium doping of calcium oxide based materials were recently reported by Sakellariou et al. (2015).
