Answer:
ExplWith NaOH you are only dissolving the material, whereas CaO reacts to make Ca(OH)2 . The calcium hydroxide has a lower solubility in water than NaOH and so will precipitate out.
Adding NaOH to Water:
NaOH + H2O = Na+ and OH- ions. The reaction will be Exothermic, where heat will be released. Sodium hydroxide is considered a strong base and as such is able to completely and fully disassociate in aqueous solution.
Adding CaO to Water :A lot of heat (exothermic reaction) is produced in the reaction, which may even cause the water to boil.anation:
