  1. Diluting Acids How to Calculate Acids in concentrated form are diluted to the desired concentration using water. Moles of acid before dilution = moles of acid after dilution Moles of acid = M x L Molarity by Dilution

  2. Formula Practice Problem M1 x V1 = M2 x V2 How much concentrated 18M sulfuric acid is needed to prepare 250mL of a 6.0M solution? Molarity by Dilution

  3. Titration – Definition Neutralization Reaction Titrations Include Analytical procedure used to determine the M of an unknown solution. Carefully controlled neutralization reaction Acid + Base = Salt + Water HCl + NaOH  NaCl + H2O Standard solution + unknown solution + Indicator Acid-Base Titration

  4. End Point Indicator changes color Moles of acid = moles of base (or molar ratio in balanced equation) Titration
