Question

Write the similarities between the reactions of NaOH in water and CaO in water.

Answer 1

The reactions of both sodium hydroxide (NaOH) and calcium oxide (CaO) in water share two primary scientific similarities. First, both processes are highly exothermic, meaning they release a significant amount of heat energy into their surroundings. Second, both substances yield hydroxide ions\[\ce{OH-}\]when mixed with water. As a result, both reactions ultimately produce strongly alkaline (or basic) solutions.
