With NaOH, you are only dissolving the material, whereas CaO reacts to make Ca(OH)

. The calcium hydroxide has a lower solubility in water than NaOH and so will precipitate out.

Adding NaOH to water:

NaOH+H

2

O=Na

+

and OH

ions. The reaction will be exothermic where heat will be released. Sodium hydroxide is considering a strong base and as such is able to completely and fully dissociate 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.
