In your kitchen, you have a vinegar bottle that indicates that it has 5% vinegar. As you wanted to see if this claim is true. You decided to do a quantitative analysis u Let's assume that you are performing an experiment in a laboratory and have all for this titration. You have collected following information. Volume of the acetic acid (CH3COOH)use for the titration = 25.0 mL Morlarity of the NaOH solution = 0.90 M Initial burette reading = 22.82 mL Final burette reading = 45.67 ml Assume density of the vinegar solution is same as the density of water (1.0g/mL) Using above information how do you prove or discard above claim (5% vinegar).
A 5.00-mL sample of vinegar was pipetted into a flask, two drops of phenolphthalein indicator were added, and the acid was titrated with 45.62 mL of 0.1008 M NaOH.
