A student rushed through this experiment, but noted some procedural errors in their lab notebook. If the following observations were listed in the lab notebook, how would they affected the calculate sodium hypochlorite percentage? Would the calculated percentage be too high, too low, or unchanged by their procedural error? A student forced the remaining liquid in the pipet out with the pipet pump. A student had an air bubble in the buret tip that remained there during the entire titration. A student had an air bubble in the buret tip that came out during the titration.
Mola and Rity were tasked to analyze the acidity of a 10.0-mL fermented milk sample diluted with water in a 250-mL volumetric flask. Mola obtained a 15.0-mL aliquot of this solution, diluted it to 50.0 mL, and then titrated this diluted sample. Titration data were given to Rity and she found out that the 50.0-mL diluted sample contains 0.21 mmol of lactic acid. MW: Lactic Acid (90.08) Follow proper significant figure rulesa. What is the lactic acid concentration (in M) of the titrated sample? b. Determine the lactic acid content (in M) of the 10.0-mL fermented milk sample. c. What is the lactic acid concentration (in %w/v) of the 10.0-mL fermented milk sample?

Considering the procedure below: “Determination of the concentration of HCl: Pipette 10 mL of hydrochloric acid and transfer to a 100 mL volumetric flask, complete the volume with water and homogenize. Remove a 10 mL aliquot of this solution and transfer it to a second dilution in a 100 mL volumetric flask, complete the volume with water and homogenize. Take a 20 mL aliquot of this last solution and transfer to a 250 mL erlenmeyr and add 20 mL of distilled water and 4 drops of the acid-base indicator. Titrate with a previously standardized 0.100 mol/L sodium hydroxide solution until the indicator turns.” Answer: a) In this titration, the indicator used is phenolphthalein. Discuss the use of this indicator considering its turning range and pH at the stoichiometric point of the titration. Justify. b) Considering that the volume of titrant used was equal to 24.5 mL, calculate the concentration of HCl in the sample in mol/L.
Chemistry Nitric acid solutions with a pH of about 5 are often used to simulate acid rain. A nitric acid solution with a pH of 5 has a concentration of 0.00001 M. Describe how to prepare 10 mL of a 0.00001 M solution using a 1 M stock solution and the serial dilution technique
In this experiment, you will take a 25.00 mL aliquot of vinegar and dilute it to 250.0 mL. You will then take a 25.00 mL aliquot from this diluted vinegar solution and titrate it against the standardised sodium hydroxide. The titration between acetic acid and sodium hydroxide is a 1:1 stoichiometry. If your standardised sodium hydroxide solution was determined to be 0.060 M, and it required an average titre (titration volume) of 20.3 mL, what is the concentration (in M) of the undiluted vinegar sample (the initial vinegar sample)? Provide your answer to 2 significant figures.

Which statement about the determination of the percentage purity of benzoic acid is correct? * A- Only sodium hydroxide solution can be used as the titrant in the volumetric analysis of benzoic acid. B- Analysing a benzoic acid sample that still contains some hydrochloric acid may yield an analyte percentage that is less than expected. C- Analysing a wet benzoic acid sample may yield an analyte percentage that is more than expected. D- All these statements are correct. E- None of these statements are correct.
