Questions and Answers

What is the purpose of standardizing a sodium hydroxide solution?

  • To determine its approximate concentration
  • To prepare it directly from the solid
  • To determine its exact concentration using a known acid solution (correct)
  • To titrate it against an acid of unknown concentration
  • What is the stoichiometric equation for the titration reaction between sodium hydroxide and oxalic acid?

  • (COOH)2 + NaOH → H2O + COONa
  • (COOH)2 + 2NaOH → H2O + (COONa)2
  • (COOH)2 + 2NaOH → 2H2O + COONa (correct)
  • COOH + NaOH → H2O + COONa
  • Why can't a standard solution of sodium hydroxide be prepared directly from the solid?

  • Sodium hydroxide is too expensive to use in large quantities
  • Sodium hydroxide is a primary standard and cannot be prepared as a solution
  • Sodium hydroxide is not a primary standard and requires titration to determine its exact concentration (correct)
  • Sodium hydroxide reacts with air to form an insoluble compound
