Of these, what is the order from highest pH to lowest pH? #LiOH(aq)#, #HBrO(aq)#, #Sr(OH)_2(aq)#, #NH_3(aq)#, and #HI(aq)#

The bases gives rise to more alkaline solution, and thus higher #pH#

Explanation:

And so from highest #pH# to lowest.........I propose...........

#Sr(OH)_2(aq), LiOH(aq), NH_3(aq), HBrO(aq), HI(aq)#.

The right hand side includes the strong acid #HI#. #HBrO# is a weak acid; ammonia, #NH_3#, behaves as a bas in aqueous solution.

Why will #Sr(OH)_2# gives a higher #pH# than #LiOH# given equal concentration?
