🤓 Based on our data, we think this question is relevant for Professor Woodis' class at Salisbury University.

Solution: Assuming equal concentrations, rank these solutions by pH from highest pH to lowest pHSr(OH)2(aq), NaOH(aq), NH3(aq), HBrO(aq), HBr(aq)Please explain with explanation.

Problem

Assuming equal concentrations, rank these solutions by pH from highest pH to lowest pH

Sr(OH)2(aq), NaOH(aq), NH3(aq), HBrO(aq), HBr(aq)

Please explain with explanation.

Solution
  • Recall that as pH value decreases, acidity increases while as pH increases, basicity increases

  • Sr(OH)2 and NaOH appear as strong base, NH3 as weak base, HBrO as weak acid while HBr is a strong acid
