Vedclass · Answer

(B) The basic strength of hydroxides depends on the ease with which they release $OH^-$ ions in an aqueous solution.$NaOH$ and $KOH$ are strong bases as they are alkali metal hydroxides.$Ca(OH)_2$ and $Ba(OH)_2$ are alkaline earth metal hydroxides.Among the given options,$Ba(OH)_2$ is more basic than $Ca(OH)_2$ because the basic strength of alkaline earth metal hydroxides increases down the group due to the increase in ionic character and solubility.Therefore,$Ca(OH)_2$ is the weakest base among the given options.

Which of the following is the weakest base among $NaOH$,$Ca(OH)_2$,$KOH$,and $Ba(OH)_2$?
