1 Lab 5 – Acid / Base Balance Definitions ± Acid - A molecule that can release H + (protons) into a solution. ± A solution containing a higher H + concentration than water is said to be acidic. e.g. HCl and H 2 CO 3 ± ACIDS DONATE H+ ± Base - A molecule that lowers the H + concentration of a solution by accepting H+. ± Most bases release OH- (a hydroxyl ion) into a solution which combines free H + to form H 2 O and thus lower the H + concentration. e.g. NaOH, KOH ± BASES SCAVENGE H+ Definitions continued ± pH scale - A scale of 0 - 14 which indicates the H+ concentration of a solution. The pH number = -log 10 [H + ], where [H + ] = molar H + concentration. pH of 7.0 = neutral, pH < 7.0 is acidic, pH > 7.0 is basic. ± Acidosis - A fall in blood pH below 7.35 (normal blood pH 7.35 - 7.45). Acidosis does not mean acidic (pH <7.0) e.g. blood pH of 7.2 is serious acidosis. ± Alkalosis - A rise in blood pH above 7.45
