Titration calculations (T)

• What is the goal of the titration calculation discussed in the video?

  To determine the concentration of an acid or alkali in moles per decimeter cubed and in grams per decimeter cubed.
• What is the first step in performing a titration calculation?

  • Write the letters C = M = MV for both acid and alkali
  • Enter the given information
• Why do we convert volumes to decimeters cubed in titration calculations?

  To standardize the units for concentration calculations.
• How do you calculate the number of moles of sodium hydroxide?

  Multiply the concentration (0.1) by the volume (0.025).
• What does the absence of large numbers in a chemical equation indicate?

  It means one mole of acid reacts with one mole of alkali.
• How do you calculate the concentration of hydrochloric acid?

  Divide the moles (0.0025) by the volume (0.017).
• How do you convert concentration from moles per decimeter cubed to grams per decimeter cubed?

  Multiply the concentration by the relative formula mass.
• What is the relative formula mass of hydrochloric acid?

  36.5 g/mol.
• What is the concentration of hydrochloric acid in grams per decimeter cubed?

  5.366 grams per decimeter cubed.
• How do you find the number of moles of calcium hydroxide?

  Multiply 0.2 by 0.025.
• How does the reaction ratio between sulfuric acid and calcium hydroxide affect the calculation?

  It means the moles of sulfuric acid are equal to the moles of calcium hydroxide.
• What is the concentration of sulfuric acid in moles per decimeter cubed?

  0.5 moles per decimeter cubed.
• What is the goal of the titration calculation discussed in the video?

  To determine the concentration of an acid or alkali in moles per decimeter cubed and in grams per decimeter cubed.
• What is the process to calculate the concentration of an acid or alkali?

  • Identify the known concentration and volume of one solution
  • Use the chemical equation to find the relationship between the reactants
  • Calculate the number of moles of the known solution
  • Use stoichiometry to find the moles of the unknown solution
  • Calculate the concentration of the unknown solution
