DETERMINATION OF THE ACID REPORT EXPERIMENT 11 Post-Lab Questions CONTENT IN VINEGAR NAME DATE Why doesn't it matter if water is added to the vinegar sample afterit has been measured? 1. How would the concentration of the vinegar solution be altered if the pipet used to dilute the original concentration of vinegar contained some water? 2. How would the concentration of the vinegar solution be altered if the volumetric flask used to dilute the original concentration of vinegar contained some water? 3. 4. If a sample of vinegar was found to be 1.55 % (m/m) acetic acid, what is the concentration of the acetic acid in molarity?

Laboratory Questions (edited) Put answers on a separate piece of paper and provide enough room for instructor comments. 1. Based on the procedure of this experiment, explain the effect of the following actions on the assessed masses of the components indicated. Where indicated, also address the effect on the percent recovery (Part D of the experiment). The choices include: lower, higher, no effect or could be higher or lower. If the answer could be higher or lower, provide a detailed explanation. a) Sublimation of NH4CI was not complete. How does this situation affect the calculated mass of NH4CI and the percent recovery? b) While decanting, some of the salty water was spilled onto the lab bench. How does this situation affect the calculated mass of NaCl and the percent recovery? c) While decanting, some of the sand was inadvertently transferred to the second evaporating dish. How does this situation affect the masses of NaCl and sand (SiO2) and the percent recovery? d) While weighing…
The concentration of a sample of dilute H2 SO4 is 4.90g dm -3 convert this to molar concentration (mol dm-3) express your answer to two decimal places use the relative atomic masses s= 32 .06, 0=16.00 and H=1.01, in calculation
1. A group of students from the instrumental analysis laboratory of the course analyzed the sodium content in a serum sample using ICP-OES.

The NaOH titrant in this experiment was prepared to be approximately 0.1 M and then was standardized to determine its exact concentration. What possible reasons could there be for not simply weighing the solid NaOH, dissolving to a known volume and calculating its molarity?
Calculate the total volume of HCl titrant delivered to the equivalence point for each trial
5. Which term is INCORRECTLY defined? a. linear range - the range over which the response of an analytical method is proportional to analyte concentration b. dynamic range concentration range over which there is a measurable response to analyte, though the response is not linear c. blank solution - a solution containing all reagents and solvents used in the analysis to which no analyte is deliberately added d. standard solutions - solutions for which the standard deviation is known - 6. True or False: Internal standards correct random error caused by run-to-run variation. a. True b. False

11. A 100.00 mL sample of orange juice, which has been fortified with calcium is titrated with 0.02357 M EDTA in the same method as this experiment. The initial buret reading is 0.15 mL and the final buret reading is 15.23 mL. How many mg of calcium are contained in the orange juice sample? Show your work. 12. What is the molarity of calcium in the orange juice sample from the above ques- tion? Show your work.
please. helpp. this unit is about chemical kinetics. PLEASEE ANSWER BOTH AS THEY ARE PART OF 1 QUESTION ONLY. I REALLY NEED HELP
