Important Equations for Tests

Molarity & Normality

  • Molarity= grams/liter
  • Normality= # equivalents x Molarity

Acid/Base Titrations

  • (M1)(V1)=(M2)(V2) 
     Acid     Base

Alkalinity

  • mg CaCO3= (normality)(Volume of acid)(1000mg/eq)(50mg CaCO3)(1/Vsln)

pH= -log[H+]

*1x10^-14= [H+][OH-]

  • Refer to the Worksheets that Dr.Carabatsos and Mr.Sanborn gave us with the equations for alkalinity!!!
