Sodium Carbonate, Sulphuric Acid and Methyl Orange Assessed Practical

Extracts from this document...


Sodium Carbonate, Sulphuric Acid and Methyl Orange Assessed Practical AS Chemistry Assessed Practical: Plan: The Apparatus to be used: A burette; conical flasks (with stopper); volumetric flask; clamp; indicator (Methyl Orange); Sulphuric acid, anhydrous sodium carbonate and distilled water; measuring cylinder; paper; weighing scale; pipette; glass stirring rod; white tile; protective wear (eye/body protection in the form of labouratory goggles and labouratory coat, plastic hand protection can be worn as well). Quantities of material to be used: Of Sulphuric acid 100ml; of anhydrous sodium carbonate 2.65grams; of distilled water 250ml and a Random [small] amount of Methyl Orange is also needed. * The Method to be used: After all the apparatus (above) ...read more.


* Now place the flask with the dissolved anhydrous sodium carbonate under the burette, fill the burette with the sulphuric acid [unknown] concentration by placing the funnel in the top opening and pouring it in. Disperse of all water bubbles - done by gently/lightly tapping burette. Record readings on burette. Use a pipette filler with a 10cm3 bulb pipette and withdraw 10 ml of the solution from the volumetric flask and transfer it into a conical flask. Add 5/7 drops of the indicator methyl orange into the solution. * Begin titration appropriately, adding the solution quickly for the first 5 seconds, the keeping to steady, quick releases of liquid, swirling the flask as you do this. ...read more.


* volume of solution (dm3). From this I cm derive what the actual concentration of sulphuric acid is, which will be recorded in mol dm-3. Safety: Protective clothing, including goggles, possibly plastic gloves and a labouratory coat. Sulphuric acid: Can cause server burns at higher concentrations, but at the lower concentrations (of which it is presumed to be between 0.05 and 0.15) can still cause irritation / rashes. Therefore if any of the solution is swilled/swallowed in mouth must be washed out medical attention obtained. If splashed in the eye run the affected eye(s) under light-running tap water for several minutes medical attention will be needed, same if spilt on skin and if on clothing remove then dabbing water on that area. If dropped in labouratory use mineral absorbent, adding anhydrous sodium carbonate to the solution leaving it to react, then adding cold water. ...read more.

    is present in the spinach extract solution and then use this to work out how much Iron (II) is present in 100 grams of Spinach Oleracea. Firstly work out the moles of Potassium Manganate (VII) (aq) in the titration. Moles = Concentration x Volume Moles = 0.025 mol dm -3


    To improve the accuracy of the results is, when heating up soil be more careful and gentle with it not to burn the soil. Next time when weighing the cooled basin make sure not to waste any of it by contaminating it.

    Any contaminant may affect the results. Using the pipette filler and keeping it in a vertical position place, the tip against the wall of the conical flask (approx 30 angle) just above the surface of the sodium carbonate solution, transfer 25 cm3 of the sodium carbonate solution from the volumetric flask into to a 250 cm3 conical flask.
