Document Summary

A hydrogen atom in a hydrogen bond between two water molecules can shift from one to the other. The hydrogen atom leaves its electron behind and is transferred as a proton, or hydrogen ion (h+) The molecule with the extra proton is now a hydronium ion (h3o+), though it is often represented as h+ The molecule that lost the proton is now a hydroxide ion (oh-) Concentration of h+ and oh- are equal in pure water. Adding certain solutes, called bases and acids, modifies the concentrations of h+ and oh- Biologists use something called the ph scale to measure this. An acid is any substance that increases the h+ (proton) concentration. A base is any substance that reduces the h+ (proton) concentration. The ph of a solution is defined by the negative logarithm of h+ concentration. Acidic solutions have ph values less than 7. Basic solutions have ph values greater than 7.
