Sodium Carbonate, Sulphuric Acid and Methyl Orange Assessed Practical

used: After all the apparatus (above) has been collected the experiment will begin as follows: The amount of anhydours sodium carbonate required, weighed on a scale (using paper), should be collected then placed in a volumetric flask. The required amount of distilled water should be added to the same 250 cm3 volumetric flask using a pipette, then the flask needs to be inverted. This can be stirred or swirled until all the solute appears to have reacted (solution should be clear). Transfer this into  a  conical flask.The burette should be attached to the clamp, leaving space at the nozzle to the conical flash and white tile can be put underneath it.The white tile and the conical flask should be placed underneath the burette. An additional, small amount of sulphuric acid should be drained through the burette into the excess flask, then discarded. 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.  Repeat six (6); experiment is complete when the solution turns a pale colour.Record final reading on burette. From the titres an average volume of sulphuric acid should be calculated within 0.1cm. Methyl Orange produces a yellowish colour in alkalise and a distinctly red colour in acids.Repeat this process, the first can be used as a test to know what type of colour is required, and how to perform experiment as correctly as possible (though this isn't necessary)11)Record all results on to a table.   All cm3 readings need to be converted into dm3 and 1dm is equal to one thousand (1000) cm3. The following formula can now be used due to the experiment I've devised : concentration (moldm-3) = concentration (in g dm ) / molar mass (in g mol). This can also be written as concentration of actual solution (mol dm-3) * 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.
