Warm-up If 45.0 mL of 2.50 M NaOH is needed to neutralize 36.0 mL of a HCl solution, what is the molarity of the acid?
Unit 10 Review Standard – 25 MC questions Honors – 15 MC (60%), and 10 short answer (40%)
Topics Covered Solutions Acids & Bases Neutralization Solution Stoichiometry Don’t lose points because of units or sigfigs!
Solutions Vocabulary: Solute, Solvent, Saturated, unsaturated, supersaturated, dilute, concentrated, volumetric flask Solubility curves solubility unit: g/100g H2O Read chart and adjust value if asked about a solution that is not 100 g of water Colligative properties (BP & OP increase, FP & VP decrease) when a solute is added. Molarity =mol of solute/liters of solution Dilutions (M1V1 =M2V2)
Acids & Bases Neutralization Reactions & Metal-Acid Reaction Properties of each The 7 Strong acids Strong bases Strong acids and bases completely dissociate. Weak do not. Identifying acids & base (Bronsted-Lowry/Arrhenius) and matching Conjugate Pairs
pH Scale pH equations (on reference sheet) pH indicators (litmus paper) Since Strong acids dissociate completely, [strong acid] = [H+] Since Strong bases dissociate completely, [strong base] = [OH-]
Neutralization & Solution Stoichiometry Vocabulary: titration, equivalence point, end point, titrant, analyte, Titration curves Neutralization calculations (titration) ***Must use Liters!!!!
