Note that B has three hydrogens bonded to it. Ironically, Wikipedia is wrong about Sn 2+: it's much more acidic in water than Ca 2+ or Zn 2+, and more acidic than Y 3+, because Sn 2+ forms very stable and non-soluble hydroxo compounds and hence readily . Acid-base reactions are called neutralization reactions because the reaction of an acid with a base generally produces a salt with little or no acid-base character and, in many cases, water. NH 4 + ions are acidic (conjugate acid of the weak base NH 3 ). Has anything like that creepy happened to you when someone you know account got hacked and knew someone else was using it?

We define acids as having a pH less than 7 and bases as having a pH above 7. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. why? One difficult aspect of acid-base chemistry is recognizing what types of species are present in solution, i.e., whether a species is a strong acid, strong base, weak acid, weak base or a neutral species. Note that there is no $\ce{OH-}$ to start with (very little in reality), so equation $(1)$ is not applicable.
