Say if you add NH3 to a solution, and it accepts a proton, it still becomes NH4+ in a solution, which is also acidic. A base should decrease the hydrogen ion concentration in a solution, but how does a solution become more basic if it now has an increased concentration of NH4+?

    $\begingroup$ When $NH_3$ accepts a proton, what molecule does the proton come from, and what does this molecule look like after losing a proton? Are there any other acids or bases in the solution, and how will their concentrations change? $\endgroup$ – Blaise Feb 8 at 18:05

    $\begingroup$ Indeed, H+ is acidic, and so is NH4+, but there is a catch. Indeed, Mike Tyson is strong, and so is an elephant, and so is a nuclear blast, and so is the black hole's gravity. One may be tempted to say they are all the same, but there is a catch. $\endgroup$ – Ivan Neretin Feb 8 at 18:57

Severe misconception. Hydrolysis reaction is NH3 + H2O --> NH4+ + OH-

Hence, dissolving NH3 in water produces OH- ions, making the solution more basic, as [OH-] > [H+]
