Did this a few weeks ago, didn't write down my method and have forgotten how to calculate it. Have got 2 answers but don't know how I reached them. I have 0.53g and 1.06g. Which one is right?
You are to find the precise concentration of a solution of hydrochloric acid. You are told that the acid has a concentration somewhere between 0.08 mol. dm-3 and 0.12 mol. dm-3 . The concentration of the acid is to be determined by titration with a solution of sodium carbonate. Using suitable calculations, suggest a suitable mass of sodium carbonate to add to water to make 100 cm3 of the standard solution. Use the information below to help you in your calculations:-
volume of volumetric flask = 100 cm3
volume of burette = 25 cm3
Volume of pipette = 10 cm3
Note that during the titration the burette should not need to be refilled.
