The issue of the total concentration of weak acid solutions
Thread Content
In the weak acid solution HAc, HAc = H+ + Ac–; the total concentration is c=+. Why are the hydrogen ions not taken into account? I’ve been working in the chemical industry for many years now; I’ve completely forgotten everything about it.
Water also ionizes to release hydrogen ions. When calculating with hydrogen ions, it needs to be subtracted, right? And since the total HAc concentration is already taken into account, why add hydrogen ions as well? Wouldn’t that be redundant?
