I know CaO is a base, however is it a strong or weak base?

It is considered a strong base because it completely dissociates when it is added to water.

how do you know what is a base if it doesn't have OH

Im pretty sure CaO is a strong base because it completely dissociates.

CaO is a strong base because it fully dissociates into its constituent components

Is this just something we would have to memorize? How do we know if it will completely dissociate in water?

I believe the -OH and -O bases formed from alkali and alkaline earth metals are typically classified as strong bases. Hope this helps!

CaO is a Lewis base, and since it is a metal oxide, it will be a strong base that, when reacting with water, will form Ca(OH)2, a strong base that entirely dissociates into Ca2+ and hydroxide ions.

strong base in solution

CaO is a Lewis base and because it is a metal oxide it will be a STRONG base that will be completely ionized (disassociated) in water leaving only Ca2+ and hydroxide ions.

CaO is a strong base because it fully dissociates to give ions in solution.
