Lesson Worksheet: Titration Calculations Chemistry

In this worksheet, we will practice using the results from a titration experiment to calculate unknown properties of a solution.


An unknown mass of CaCO3 was dissolved to make up a solution of 80 mL. Upon titration, it was found that 60 mL of 4 MHCl completely neutralized the CaCO3 solution.

What was the concentration of the CaCO3 solution?

What mass of CaCO3 was dissolved in the solution? Give your answer in grams.


What volume of a 3 mol/dm3 solution of ammonia would be needed to completely react with 70 cm3 of a 2 mol/dm3 solution of hydrochloric acid?


The table below shows the results of titrating 0.02 dm3 of barium hydroxide Ba(OH)2 against 0.2 M of hydrochloric acid. Using the results in the table, and discounting any anomalies, determine the concentration of Ba(OH)2. Give your answer to 2 decimal places.

20 cm3 of an unknown concentration of acetic acid (CHCOH)32 was placed in a conical flask and titrated against 2 M of sodium hydroxide. The change in pH as sodium hydroxide was added was recorded and is shown below.

What approximate volume of sodium hydroxide neutralized the acetic acid?

  • A3.0 cm3
  • B4.0 cm3
  • C7.5 cm3
  • D12.0 cm3
  • E8.2 cm3

What was the concentration of the acetic acid solution?


A student sets up an experiment to measure the pH of a solution during titration. A 50 cm3 solution of NaOH of unknown concentration is neutralized by the addition of 1 MHCl. The results of the experiment are shown in the graph below.

What is the approximate volume of HCl required to neutralize the sodium hydroxide solution?

  • A70 cm3
  • B21 cm3
  • C55 cm3
  • D40 cm3
  • E33 cm3

What is the concentration of the sodium hydroxide solution?


A student performed a titration and recorded the volume of acid needed to neutralize a base. The experiment was repeated five times and the results were collected in a table. Which result of repeated titration can be considered an anomaly?

Volume of Acid (cm3)17.817.916.817.618.0


A student attempts to determine the concentration of citric acid in an orange. 20 mL of orange juice is titrated against 0.1 M of sodium hydroxide. The following is an equation for the chemical reaction: 3NaOH+CHONaCHO+3HO68736572 The student finds that 6.0 mL of sodium hydroxide neutralizes the citric acid. What is the concentration of citric acid in the orange juice? Give your answer in millimoles per cubic decimeter.


A titration experiment is performed 7 times. The first titration is used as a rough estimate of where the end point may be, whilst the remaining six titrations are used to try and provide an accurate measurement. What is the average titer volume? Give your answer to 2 decimal places.

Volume Added (cm3)21.819.219.417.619.118.920.6


A titration is set up to determine the concentration of an ammonia solution. 75 cm3 of ammonia was placed in a conical flask and a few drops of methyl orange indicator were added. A solution that was 0.4 M sulfuric acid was then titrated into the conical flask. The color of the solution near the end point is shown below.

What volume of sulfuric acid completely neutralized the ammonia solution?

What was the concentration of the ammonia solution? Give your answer to 4 decimal places.


Calculate the concentration of 0.450 mol/LBa(OH)2 in grams per cubic decimeter (g/dm3). Give your answer to 1 decimal place.
