A solution of Ba (OH), was standardized against 0.1208 g of primary-standard-grade benzoic acid, C6H5 COOH (122.12 g/mol). An end point was observed after addition of 43.94 mL of base. a. Calculate the molar concentration of the base. Concentration =| M b. Calculate the standard deviation of the molar concentration if the standard deviation for the mass measurement was +0.4 mg and that for the volume measurement was +0.02 mL. Standard deviation = M c. Assuming an error of -0.3 mg in the mass measurement, calculate the absolute and relative systematic error in the molar concentration.

Introductlon In Part (a) of this experiment you will prepare a primary standard. Potassium hydrogen phthalate (KHP) is a monoprotic acid with the formula KHC,H.O. In this experiment KHP is used as the primary standard. A standard solution is one whose solute concentration is accurately known. If a solute can be obtained in a very pure, stable, weighable form, a primary standard solution of it can be prepared directly. You will then use the standardized sodium hydroxide solution to determine the acetic acid content of a dilute unknown solution. Procedure (0) Preparation of a Primory Standard Potassium hydrogen phthalate (KHP) is a primary standard. Weigh accurately by difference, approximately 0.8 g of KHP in a clean, dry weighing bottle and transfer it into a 250 ml conical flask. Add 75 ml of distilled water. Swirl gently. Cover the flask and leave to dissolve, swirling periodicaly. Cautlon: KHP is not highly soluble and care must be taken to ensure it is all dissolved before you…
© Macmillan Learning Five standard solutions of a newly discovered inorganic salt were used to create a calibration curve. The density (g/mL) of each solution was plotted on the y-axis versus the % (w/v) concentration on the x-axis. The calibration curve was linear and fitted with the following best-fit line. y = 1.17x + 0.188 A student is asked to analyze a solution of this salt with a density of 4.00 g/mL. What is the concentration, in %(w/v), of the unknown salt solution? concentration: % (w/v)
Note: This is an algorithm question so each attempt will have unique set of measurements. The following results were obtained when a sample of white cranberry juice was analyzed to determine its Vitamin C content. A 82.0 mL sample of the juice was placed in a flask with excess H2SO4, excess KI, and 11.00 mL of 0.07 000 M KIO3. Titration with thiosulfate solution required the use of 1.63 mL of 0.08826 M. Calculate the concentration of Vitamin C in the juice sample as mg Vit C per 100 mL juice. Here are some steps to help you work your way along the problem. All the reactions in the Background apply. • How many total millimoles of I are produced from the Reaction 4 between KI and KIO3? • How many millimoles of I are consumed in Reaction 3 with thiosulfate? . Using your previous two answers, how many millimoles of I reacted with the Vitamin C in the juice? • How many milligrams of Vitamin C were in the juice sample? • What is the concentration of Vitamin C in the juice sample expressed as…
