#### Answer

Amphoteric: may act as an acid and a base $K_w$ reaction: the autoionization of water $K_w$ equilibrium constant: the ion-product constant for water $pH$: the negative logarithm of $[H^+]$, the concentration of $H^+$ ions $pOH$: the negative logarithm of $[OH^-]$, the concentration of $OH^{-}$ ions $pK_w$: the negative logarithm of the ion-product constant of water (equal to 14 at 25 degrees Celsius)
