Why is it important to remove the CO2 from the solutions before doing the titration?
It is important to remove the carbon dioxide from the solutionf before doing the titration because, carbon dioxide mixed with water is acidic, it produces an acid.
Is it necessary to rinse the conical flask with some standard solution of oxalic acid before use?
I believe it is necessary to rinse the conical flask with oxalic acid before use, unless you are sure that the conical flask is really clean and dry before use. However to prevent having any types of unwanted chemical reaction when you pour the oxalic acid in the flask, it is best to rinse it with oxalic acid before use, so that there will not be errors like e.g. there is no pinkish color formed in the solution when you add the color indicator in the oxalic acid when doing titration.
How do you get an accurate titration?
In Titration, to make sure we get a reliable and accurate result at first we will do a rough titration and we would do this by balancing the weigh boat to 0.00, use exact 2.5g of potassium carbonate, make sure the stopper your using is not broken and test it before using it. Look carefully at position of meniscus and it should be read from eye level. Raising the burette and glass pipette for every activity will help to reduce contamination, by doing these procedures we will get accurate results. After 25.9 cm make it drop by drop, to reduce the human error, there should be more than one person to do the experiment so they can get the timing right. Before using the conical flask, water it with distilled water
When doing a titration in chemistry why do you weigh by difference?
you weigh by difference to minimise the amount of errors because essentially all scales have the same ammount of error on them.
Why do you swirl the Erlenmeyer flask?
To mix the reactants. Assuming you have been doing a titration experiment and I am doing your homework its so as you add the acid/alkali you can accuratly close the biuret when the indicator changes colour.

How do you make 100g of glucose?
from what? water and sugar. Like the drink they give you for the glucose Tolerence test
Why were you instructed to keep swirling the flask?
To mix the reactants. Assuming you have been doing a titration experiment and I am doing your homework its so as you add the acid/alkali you can accuratly close the biuret when the indicator changes colour.
