Why does aqueous KBr has neutral pH?

If you look at KBr, it gives off neither H+ ions nor OH- ions, because K+ does not act as an acid and Br- is a neutral conjugate base, causing KBr overall to be neutral.

KBr dissociates into K+ and Br-. K+ is a neutral cation and Br- is the conjugate base of a strong acid so it is also neutral. Since neither ion reacts further, the solution will also be neutral.
