Acid Base Reactions

These types of reactions will produce a water and a salt, and the water produced is the driving force of this reaction.
Here's a small example of what it would look like:

Within the acid-base reaction, there is a possibility for both strong acids and bases, as well as a weak version of both. Strong acids produce H+, protonate completely, HCl, HBr, HI, and are the strongest if the oxygens outnumber the hydrogens by 2 or more. Strong bases contain an -OH- anion, disassociate completely, all group 1 and 2 metals plus the -OH anion are the strongest. Weak acids do not protonate completely, are not on our memorized list Weak bases do not disassociate completely, are not on our memorized list
A good thing to remember is when looking at the molecular diagram, to always look for the parents. If there are more parents, this means it is weak, or if there are less, it is strong.
