46. A multivitamin sample has a label claim of 500 mg ascorbic acid (176.12 g/mol). According to quality assurance guidelines for stability, it has an acceptable range of 90.0%-110.0% of the label claim. After production, the multivitamin was analyzed through acid-base titration, and the sample needed 25.40 mL of a 0.1101 M NaOH titrant to reach the end point. After 3 months, the same multivitamin was analyzed again, and this time 23.34 mL of the same 0.1101 M titrant was used. After 6 months, the same multivitamin was analyzed again, and this time, 22.48 mL of the same 0.1101 M NaOH titrant was needed to reach the end point. How many mg of ascorbic acid are present in the 6 month old sample?
Please using the data below please do the calculations in the image attached Both images go together Please please answer super super fast it's super important
Chemistry write introduction Experiment Acid-Base Titration Using a pH Meter and Phenolphthalein Strong acid vs Strong base should state the purpose of the investigation and must include appropriate citations of relevant, precedent work but should not include an extensive review of marginally related literature. If the manuscript describes a new method, indicate why it is preferable to older methods. If the manuscript describes an improved analysis of a substance, the competing methods must be referenced and compared. use Hydrochloric acid
A student performed a titration on a commercial acid certified to be 0.500 M. Using her data from the titration, the student determined her sample to be 0.487 M. Assuming the certified value was the true value, what was the percent error of her measurement?
Given for nos. 10-11: In an acid-base titration, you were given with a 0.1050 M sodium hydroxide solution placed in a buret and is needed to neutralize 20.0 mL of 0.1500 M sulfuric acid. 10. How much moles of sulfuric acid is found in the 20.0 mL solution of a 0.15M H2SO4? Answer: Computation: 11. What volume of 0.1050 M sodium hydroxide solution is needed to neutralize 20.0 mL of 0.1500 M sulfuric acid? Answer: Computation: 12. Draw and label a complete laboratory set-up of acid-base titration using phenolphthalein as the indicator, using HCl as the analyte/sample, and using NaOH as the standard solution. Cite complete source/(s) if picture will be copied from the internet.
