  1. Electrolytes are
    Substances that release ions in water
  2. Acids are
    • Substances (electrolytes) that dissociate to release hydrogen ions (H+) in water
    • Ex: HCL (hydrochloric acid)--> H+ + CL-
  3. Bases are
    • Substances (electrolytes) that combine with hydrogen ions
    • Ex: H+ (acid) + OH- (base)--> H20
  4. Salts are
    • Substances formed by the reaction between an acid and a base
    • Ex. HCL (acid) + NaOH (base) --> NaCL (salt) + HOH (water)
  5. pH Scale is
    • a shorthand system used to indicate the concentration of hydrogen ions, pH scale ranges from 0 to 14. Normal/ neutral pH is 7.0. Acidic solutions have pH values less than 7.0, alkaline solutions have pH values that are more than 7.0
  6. Alkalosis is
    blood pH above 7.45
  7. Acidosis is
    blood pH below 7.35
  8. Buffers are
    chemicals that resist pH change
  9. Carbonic acid dissociation formula is
    CO2+H2O--><--H2CO3--><--H+ + HCO3-
