Introduction

Plan for the practical Assessment Aim - to find the accurate concentration of Sulphuric (VI) Acid that has a concentration between 0.05 and 0.15 mol dm� Apparatus 1. Standard Solution Scales 250cm� Volumetric Flask 100cm� Beaker 2. Titration Clamp Stand Burette Pipette Filler Beaker White Tile (iii) Chemicals Distilled Water Calcium Carbonate Sulphuric Acid Method for finding the Standard Solution 1. Calculate the mass of 1 mole of Sodium Carbonate by adding together the element's relative atomic masses, which can be found on a periodic table. 2. Calculate the mass of 0.1 moles of Calcium Carbonate. This is done by using the mass of 1 mole (calculated in step 1) ...read more.

Middle

As it is impossible with the equipment given to get exactly the right mass, note down the actual mass, given by the scales, to three decimal places. 5. Add 100cm� of distilled water to the weighed out Sodium Carbonate and stir until you cant see anymore Calcium Carbonate as it has all dissolved. Pour this into the 250cm� volumetric flask and fill up to the 250cm� line with distilled water. 6. After you have done this you can find the actual concentration of the solution by using the following equation: Moles of Sodium Carbonate in 250cm� = Mass dissolved Mass of 1 mole The second half of this experiment is titration. ...read more.

Conclusion

If it is swallowed, wash out mouth and give one or two glasses of water. Don't induce vomiting. Seek medical advice as soon as possible. If it is splashed into the eye flood the eye with gently running tap water for 10 minutes. Seek medical advice If it is spilt on clothes or skin remove the clothes quickly and wipe as much liquid as possible away with a dry clothe before drenching the area with lots of water. If a large area of skin was affected or blistering seek medical advice. If it is spilt in the laboratory, wear eye protection and gloves and cover with mineral absorbent and scoop into a bucket. Add anhydrous sodium carbonate and leave to react. Once the reaction has occurred add lots of cold water. ...read more.

    * Place the funnel into the 50.00cm3 burette. Ensure the burette tap is closed and fill the burette with the aqueous sulphuric acid. Record the initial burette reading. * Pipette 25.0cm3 of the Sodium Hydroxide solution into a 25.0cm3 conical flask. * Add 2-3 drops of the Methyl orange indicator to the conical flask * Run the aqueous

    Similarly I could have made some parallax errors while reading off the values from the scale. In addition some technical mistakes might have been made while producing sodium carbonate, for instance some of the initial anhydrous sodium carbonate might not have been mixed fully with 250ml of water and a small portion of solid particles might have remained behind.

    Pour further distilled water into the beaker until the beaker is filled half way(150cm3) 7) Used the glass rod to stir the solution until the solid has dissolved. 8) Transfer the solution into Graduated volumetric flask using a funnel so that all the solutions get into the flask. 9)

  2. How to find the accurate concentration of the Sulphuric Acid.

    -As soon as there is a colour change in the conical flask, stop adding the Sodium carbonate solution. -Take a final reading from the burette to work out how much solution was needed to neutralise the Sulphuric Acid. Then use this to work out the concentration of the ammonia in the conical flask.
