est questions. Therefore, you are to attach your Excel sheets in your submissions. Notably, it is important for you to present calculations in Excel that can be easily understood when I am marking your submissions. Please be reminded to attach a submission T page to your assignments and to submit your work through Turnitin on iLearn. For those living near to the University, it will be a big help if you can provide me with a hardcopy of your work. 1. You determine the acetic acid (HOAc) content of vinegar by titrating with a sodium quilooo ul (A hydroxide standard solution to a phenolphthalein (an indicator) end point. An approximately 5-mL sample of vinegar is weighed on an analytical balance in a weighing boat and this is found to be 5.0268 g. The standard deviation in making a single weighing is 0.2 mg. show ofdo The sodium hydroxide must be accurately standardised (this means its concentration must wold be accurately determined) by titrating known mass of high-purity potassium hydrogen tes wal pri phthalate, and three such titrations give molar concentrations of 0.1167, 0.1163 and BuDUPE 0.1164 mol L-1 ofster bas barssquad ON980 2958GHB A volume of 36.78 mL of sodium hydroxide is used to titrate each sample. The standard deviation of the burette used is 0.02 mL. Calculate the percentage of acetic acid in the vinegar and its standard deviation
