Acids

Sulfuric Acid – H2SO4

  • pH and hydrogensulfate concentration of 1.2 mM sulfuric acid.
  • pH after dilution of 40 mL of 2.5 molar H2SO4 to 2 L.
  • pH of strong acids (HCl, HNO3, H2SO4) without and with ionic activity corrections.
  • Acidification of a groundwater sample from pH 6.9 to 3.

Hydrochloric Acid – HCl

  • pH of an extremely diluted acid (10-8 M HCl).
  • pH of strong acids (HCl, HNO3, H2SO4) without and with ionic activity corrections.
  • pH after mixing of 100 mL of 0.01 molar HCl with 50 mL of 0.05 molar NaCl.
  • Addition of 0.2 mM HCl to a given water sample.
  • Titration of HCl with NaOH.

Nitric Acid – HNO3

  • pH of strong acids (HCl, HNO3, H2SO4) without and with ionic activity corrections.
  • Acidification of a groundwater sample from pH 6.9 to 3.
