"WebThe Brønsted-Lowry definition: Brønsted argued that all acid-base reactions involve the transfer of an H + ion, or proton. Water reacts with itself, for example, by transferring an H + ion from one molecule to another to form an H 3 O + ion and an OH - ion. According to this theory, an acid is a "proton donor" and a base is a "proton acceptor ... " - Ph of oh- 1x10-4

This is an important trick that must be remembered for the real DAT. When the concentration of HCL is smaller than 1x10-7 you have to consider water! Water has a [H] of 1x10-7 and thus if you add [HCL] 1x10^-8 you actually have a combined [H] of 1.1x10^-7. the the negative log of this is just under 7 ===> 6.98.
