HClO4 is strong acid. pH VERY low.
HBrO is a weak acid. pH higher than HClO4 but still lower than 7.
NH3 is a weak base. pH slightly more than 7 (maybe 8.5-10).
Ca(OH)2 is strong base. Greater than NH3 but less than KOH.
KOH is a very strong base and is VERY much higher than all of the others.
Assuming equal concentrations, rank these solutions by pH: hclo4 caoh2 NH3 koh hbro
