+ Cl- (aq) Here HCl gives proton H+ and acts as acid, while H 2 O accepts proton and acts as base. I hope now you can find their respective conjugate. HCl has its conjugate base Cl-and H 2 O has its conjugate acid OH-. In the above two equations you have seen that H 2 O acts as acid when it comes with NH 3 and acts as base when it comes with HCl.

Thus, I-will lose H+ ions easier than Cl-, although both are strong acids. 5) What is the strongest base in this set? Explain. I-or Br-
