How do you titrate citric acid?
- Record the mass of the bottle and its contents.
- Titrate the solution in the Erlenmeyer flask by adding drops of solution from the drop-dispensing bottle. Hold the bottle upside down over the mouth of the flask. Count drops. Swirl the flask gently.
How do you do a titration step by step?
Terms in this set (7)
- fill the burtte with known concentration of an acid or base.
- take a burtte reading from the top of the miniscus.
- place a flask with a unknown concentration of acid or base under the burtte.
- add a few drops of the appropriate indicator to the flask.
- slowly add your titrate to the flask while stirring.
What is the experimental procedure for titration?
Use the pipette and pipette filler to add 25 cm 3 of alkali to a clean conical flask. Add a few drops of indicator and put the conical flask on a white tile. Fill the burette with acid and note the starting volume. Slowly add the acid from the burette to the alkali in the conical flask, swirling to mix.
What is a titration procedure?
A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. Typically, the titrant (the know solution) is added from a buret to a known quantity of the analyte (the unknown solution) until the reaction is complete.
How is citric acid measured?
In the case of the citric acid titration, a known amount of orange juice is measured into an Erlenmeyer flask with an indicator solution containing phenolphthalein (the indicator). Sodium hydroxide, at a known concentration, is then carefully added into the sample until all of the acid has reacted.
How do you calculate the normality of citric acid?
Normality Formula
- Normality = Number of gram equivalents × [volume of solution in litres]-1
- Number of gram equivalents = weight of solute × [Equivalent weight of solute]-1
- N = Weight of Solute (gram) × [Equivalent weight × Volume (L)]
- N = Molarity × Molar mass × [Equivalent mass]-1
How do you record titration?
Record your final volume from your burette. Once you’ve reached the endpoint of your titration, close the stopcock and record the final volume of your titrant in the burette. Subtract your final volume from your starting volume to get total volume of titrant added.
How do you present titration results?
Draw a table to represent the results of your titration. It is customary to write the final burette volume in the first row, the initial burette volume in the second row and the titre in the third row. The titre is calculated by subtracting the initial volume from the final volume.
