- In order to obtain 3.500 % of acetic acid, what weight of a sample must have been taken for analysis if the vinegar requires 20.50 mL of 0.1150 N KOH solution for an end point of phenolphthalein indicator? Note: - Please make it handwritten - Also, include up to 4 decimal places in computing Thank you!5..A 2.25 g sample of butter was refluxed with ethanolic KOH and required 18.6 mL of 0.1978 M HCl to reach the phenolphthalein endpoint. If the blank determination 47.1 mL of the same standard acid, a. Calculate the saponification value of the sample b. Assuming that the sample comprised mainly of fat, what is its molar mass?
- In the procedure below for a weak diprotic acid titation experiment what are the independent, dependent, and controlled variables? Prepare your Buret• Condition a 50 mL buret (2x with DI H2O followed by 2x standardized NaOH)• Fill the buret with the standardized NaOH close to but not exactly 0.00 mL Prepare Your Analyte • Your analyte will need to be placed in a 250 mL beaker and should contain thefollowing:*0.5 – 0.75 g KHP** About 100 mL DI water* Magnetic stir bar• Once all contents are in the 250 mL beaker, stir for at least 5 minutes to dissolve. Ifneeded, add a bit more water.* For unknown diprotic acids, use the mass provided by the instructorNext Run the Titration (note you will need to run the titration several times for data collection so you are able to use the average molar mass to find the unknown diaprotic acid).Need these plz16.14
- A sample containing 0.450 g of nicotinic acid, a monoprotic acid, required 34.74 mL of 0.1053 M NaOH to titrate the sample to phenolphthalein endpoint. What is the molar mass of the nicotinic acid?Are any of the following true at the equivalance point? The analyte is present in excess, the titrant is present in excess, both the analyte and titrant are present in excess, neither the analyte or titrant is present in excess, the yield is 50%If the amount of NaOH used in the titration against above HCI, was 26.7 ml, calculate the number of moles of NaOH at the end-point of the titration. (Give your answer to 2 significant figures)
