which one of the following is a strong base? a mg(oh)₂ b ca(oh)₂ c nh₃ d ch₃oh
Answer
Brief Explanations:
A strong base completely dissociates in water. $Mg(OH)_2$ is a sparing - soluble base. $NH_3$ is a weak base as it only partially ionizes in water. $CH_3OH$ is an alcohol and not a base. $Ca(OH)_2$ is a strong base and dissociates completely in water to give $Ca^{2 + }$ and $OH^-$ ions.
Answer:
B. $Ca(OH)_2$
