Explain how the following scenarios would affect the experimental Ksp value (lower, higher or no change from acceptable value): ( the chemical used in this titration are Calcium Hydroxide, and the indicator used in this experiment are methyl orange indicator solution)

a) The accidental transfer of some solid Ca(OH)₂ into the titrating flask.

b) The endpoint of the titration is surpassed.

c) The Ca(OH)₂ solution was not saturated.

d) Tap water instead of distilled water was used to make all of the solutions.

e) Adding distilled water to the titrating flask to wash the sides of the flask and the buret tip.

Expert Solution

a) The accidental transfer of some solid Ca(OH)₂ into the titrating flask.

So, higher the Ksp value then the accidental transfer of some solid Ca(OH)₂ into the titrating flask.

b)The endpoint of the titration is surpassed.

higher the Ksp value then the endpoint of the titration is surpassed.

c) The Ca(OH)₂ solution was not saturated.

Higher the Ksp value then the Ca(OH)₂ solution was not saturated.

d) Tap water instead of distilled water was used to make all of the solutions.

Higher the Ksp value then Tap water instead of distilled water was used to make all of the solutions.

e) Adding distilled water to the titrating flask to wash the sides of the flask and the buret tip.

Lower the Ksp value then Adding distilled water to the titrating flask to wash the sides of the flask and the buret tip.

How would the following experimental errors affect your experimental results while separating the components of a counterfeit pharmaceutical (yield, purity or both) and explain why. A) you failed to dry the product completely. B)you used enough water to recrystallise phenacetin, however your Unknown was acetanilide. C)in experiment 1, you didn't extract all of the aspirin from DCM solution.

How would each of the following scenarios likely affect (that is, exacerbate (that is, make a bad situation worse) or mitigate (that is, make it less painful or severe) the occurrence of a financial crisis (explain briefly): Fearing potential contagious effects, the IMF suggests that it stands ready to bailout a country which may face a financial crisis. b. The threat of an eventual intervention by the IMF demanding that the country that is about to face a financial crisis...

1. Explain how different experimental errors can affect the reported value of Keq.

1. Explain how different experimental errors can affect the reported value of Keq. Clearly state why the reported value of Keq would be bigger or smaller than the actual value. Examples may include: a) You thought the spectrometer was set to read trasmittance/absorbance at a wavelength of 447 nm, but it was actually set at 520 nm. b) You thought you measured the transmittance/absorbance in a cuvetter with a 1-cm pathlength, but it was actually 1.5 cm. 2. Would...

How will the following situations affect your final calculation of molarity of HC2H3O2? (higher, lower, unaffected. be specific) A) You wash the sides of the flask with deionized water to remove any vinegar of NaOH solution adhering to the side of the flask. B) You add 20 mL of water to the vinegar in the flask (assume no drops of vinegar adhere to the side of the flask). C) The tip of the buret is not filled when you start...

Consider the following scenarios: Scenario A: Pizza is produced in slightly higher quantities, with slightly lower prices than in Scenario B. All pizza is of the same brand, served in similar types of restaurants, with no variation in quality. Scenario B: Pizza is produced in slightly less quantities, with slightly higher prices than in Scenario A. Consumers have more variety and choice, with many different types and styles of pizza made at different restaurants. a) For each Scenario, identify the...

Briefly explain how each of the following would likely affect the value of the dollar and the exchange rate, all else being equal. (Please answer for all 5!) 1. U.S. consumers increase their spending on imported goods. 2. The Federal Reserve reports that it is less concerned about inflation and more concerned about the impending recession in the United States. 3. The U.S. government imposes a large tariff on imported automobiles. 4. The Federal Reserve raised interest rates fearing inflationary...
