Document Summary
Dissociates to yield hydrogen ions in solution. When the atom loses its electron to become a h+, all that remains is the nucleus. Hydrogen ions are referred to as protons. Bases either dissociate itself in h2o to produce oh and a vacation. Or a base can split water to form a cation and oh. In pure water, the concentrations of h+ and oh- are equal. H2o tends to slightly dissociate into hydrogen and hydroxide ions. When an acid is added to a solution - increases h+ concentration. Acidic solutions have an elevated h+ and reduced oh- Ph scale - a shorthand notation for proton concentration of a solution. Pure water has a ph of 7. The ph of most living cells is usually 7. 2 - 7. 4. Accepts h+ when they are excess in solution. Made of a weak acid or base + its conjugate pair. Buffers - minimize changes in the concentrations of h+ and oh- in a solution.
