Answer 2

HBr and NH₃ will have the highest pH at equivalence point.

Explanation:

• The pH of any solution determines the $H^{+}$ ion concentration.
• Strong acids have lower pH value.
• While doing acid vs base titrations, the pH of the solution decreases and after reaching the equivalence point, it increases.
• For syrong acids and strong bases the pH value is low.
• But for strong acid the pH at equivalnece point is higher, HBr is a weak acid and ammonia is a weak base. So, they will have the highest value of pH at the equivalence point.
