How would the following errors change the calculated value of the percent oxalic acid in the radiator cleaner, that is would the calculated value of the percentage be high, low, or unchanged? Give a brief explanation of your reasoning. a. The experimenter consistently overshot the endpoint (i.e. added too much NaOH solution), of the titrations used to standardize the sodium hydroxide solution. b. The KHP used to standardize the NaOH was not pure, but contained approximately 10% by mass of the inert ionic compound potassium chloride, KCl.

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?
Would the molarity of HCl as determined in this experiment be too high or too low if:The buret is contaminated with an acid solution. The buret contains a large air bubble in the tip, which disappears in the course of the titration.
If water was used to rinse the conical flask used for the titration, how would this affect your final estimate of hydrochloric acid concentration? (More, less or unchanged?) Explain why, discussing the number of moles that you would actually have due to the rinsing
What factor affects the ‘strength’ of a buffer? Why was benzoic acid used as a solvent when making up the glucose stock standard solution?
Please help me with these questions 1. How is the molar concentration of OH- measures in a saturated Ca(OH)2 solution for this experiment? 2. How many times should a burette and / or piper be rinsed before it is used to deliver a solution for an analysis 3. Explain how to add less-than-a-drop of titrant from a buret? 4. What criterion is used to determine whether or not a buret, piper, or any other form of glassware is clean?
In the experiment of the acid dissociation constant of a weak acid using potentiometric titration, what primary standard was used to standardize NaOH in this experiment? Give the appropriate equation for the reaction.
Mention what error would be introduced in the analysis if the primary standard (KHP) is not properly dried.
A suitable target for the titration is 30.0 cm3 of 0.025 moldm-3 Br2(aq) Justify why a much smaller target titre would not be appropriate Calculate the amount in moles of bromine in the target titer Justification? calculate a suitable massof alive oil to transfer to the volumetric flask using your answer to of above question and the structure of Y Assume that the olive oil contains 85/- of Y by mass (If you were unable to calculate the amount of bromine in the target titer,you should assume it is 6.25×10^-8 mol .this in not the correct amount)
Why should be solution of sodium bicarbonate be boiled during titration with HCI?
Explain how the reported solubility product of borax will be affected if some of the solid borax is inadvertently transferred into the Erlenmeyer flask and included in the titration analysis.
Why do we use a solid acid as a primary standard? During the standardization of NaOH, Shane didn’t notice that there was an air bubble in the tip of the buret when they started their rough titration. The bubble went away during the rough titration and Shane continued with two fine titrations. Does this affect the calculated concentrations of NaOH? Why or why not?
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).
