... Water of the correct quality is essential for life. For humans, drinking water should have sufficiently low levels of dissolved salts and microorganisms. This is achieved by choosing an appropriate source, passing the water through filter beds to remove any solids and then sterilising with chlorine. ...

Weak Acids and Bases Practice -- Chemistry 121A
... OK, what’s new here really is just percent ionization. The way to think of this is that it is just a form of percent yield. It runs from 0% (all reactants) to 100% (all products). This is simply more convenient than Q, which runs from 0 to infinity. The way I look at it is this for a weak acid: %ion ...
