2 Neutralization Reactions Acid + Base Water + saltHydronium ions + hydroxide ions water + waterH3O OH H2O H2OExamples:HCl + NaOH H2O + NaClH2SO4 + 2KOH 2H2O + K2SO4All neutralization reactions are double displacement reactions
3 Titrations Standard Solution Titration End Point The solution of known concentrationTitrationThe process of a specific amount of a known solution to an unknown solution to determine the molarity of the unknown solutionEnd PointWhen the indicator shows that neutralization has occurred
5 Sample ProblemA 25mL solution of H2SO4 is completely neutralized by 18mL of 1.0 M NaOH using phenolphthalein as an indicator. What is the concentration of the H2SO4 solution?H2SO4 + 2NaOH 2H2O + Na2SO425mL H2SO4 1L H2SO mol H2SO4 2 mol NaOH mL = 0.36M NaOH1000mL L H2SO mol H2SO mL NaOH LUse stoichiometry to go from mL of your known solution to find Molarity (mol/L) of your unknown solution
