Explain the similarity and difference in two events, namely adding NaOH to water and CaO to water
Answers
Explanation:
NaOH is a monoacidic base. and CaO is a Di-Acidic base. 3) NaOH, CaO should be added to water gradually with constant stirring. CaO on reacting with water produces a basic solution called Calcium hydroxide which is used for whitewashing and this reaction is more dangerous as compared to NaOH.
Answer:
With 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.
