This tag should be applied to questions concerning acid and base reactions. An acid is capable of donating a hydron/ proton (Brønsted acid) or capable of forming a covalent bond with an electron pair (Lewis acid). A base on the other hand is a chemical species/ molecular entity having an available pair of electrons capable of forming a covalent bond with a hydron/ proton (Brønsted base) or with the vacant orbital of some other species (Lewis base).

Iterative method for calculating pH of a weak acid / base
The correct equation for determining the value of $x$, as noted by ringo, is $$2.22\times10^{-2}=\frac{[x]\cdot[x]}{[0.20-x]}$$ With a $K$ value sufficiently low, you can ignore the $x$ value on the b …
