How To Do Titration Calculations

This video tutorial covers titration calculations, demonstrating how to determine the concentration of an unknown solution using known values. It includes two examples: one using a straightforward calculation and another considering reaction proportions. The tutorial also provides a formula for quick calculations and emphasizes understanding the underlying concepts. A practice question is included for self-assessment.

What is the first step in calculating the concentration of an unknown solution in a titration?

• Measure the temperature of the solution

• Determine the pH of the solution

• Calculate the number of moles of the unknown solution

• Convert volumes to cubic decimeters

Which formula can be used to find the concentration of an unknown solution?

• Concentration of unknown = Volume of unknown x Concentration of known

• Concentration of unknown = Volume of known x Volume of unknown

• Concentration of unknown = Concentration of known x Volume of known / Volume of unknown

• Concentration of unknown = Volume of known / Volume of unknown

Why might using a formula alone not earn full marks in an exam?

• It is too complicated

• It is not applicable to all reactions

• It does not demonstrate understanding

• It requires additional calculations

In the reaction between sodium hydroxide and sulfuric acid, what is the mole ratio?

• 3:1

• 2:1

• 1:2

• 1:1

What is the concentration of sulfuric acid if 0.01 moles of sodium hydroxide react with 0.04 cubic decimeters of it?

• 0.25 mole per cubic decimeter

• 0.125 mole per cubic decimeter

• 0.5 mole per cubic decimeter

• 0.1 mole per cubic decimeter
