kw

Each system produces about 25 kw which is enough to power about 10 homes.

So the formula for Kw becomes simply the hydronium ion concentration times the hydroxide concentration.

But we can also use the Kw and the hydronium ion concentration to do a very simple division problem and find the hydroxide concentration.

For instance, words like quit, question, quarter, etc, were pronounced with the familiar " kw" sound in Anglo-Norman (and, subsequently, English) rather than the " k" sound of Parisian French.
