hydrogen atoms…
easily lose an electron to become a hydrogen ion (H+). extremely reactive in solution
pH
potential of hydrogen- concentration of hydrogen ions in a solution
neutral pH
balance of H+ and OH-. 7.0
acidic pH
high H+concentration, low OH- concentration. lower than 7.0
basic (alkaline) pH
low H+ concentration, high OH+ concentration. higher than 7.0
pH of human blood
range from 7.35 to 7.45
pH scale
inverse relationship with H+ concentration.
more H+= lower pH
less H+= higher pH
acid
a solute that adds H+ to a solution. strong ___ dissociate completely in a solution. proton donor
base
a solute that removes H+ from a solution. strong ___ dissociate completely in solution. proton acceptor
weak acids and weak bases…
fail to dissolve completely. help to balance the pH
buffers
stabilize pH of solutions. often involve a weak acid and its related base
