Post Laboratory Questions
Compare your observations of the conductivity of dry sodium chloride and a solution of sodium chloride. What conclusions can you make about these observations? Interpret your observations; do not just restate what you saw. Keep in mind the conductivity, if any, of the water used to prepare the solution.
Suppose that Part II of the experiment were carried out with aqueous NaOH (sodium hydroxide) instead of Ba(OH)2 to form soluble Na2SO4
Determined an aliquot of 0.03526M potassium permanganate solution required to make 100 mL of a 10-3 mol/L solution.
Which is the major contributor to the linewidth, T2 or T2inh? Discuss the assumption that T2=T1 for NMR. This is not true for other types of spectroscopy(electronic for instance).
At what point is the temperature in degrees farenheit exactly twice in degrees celsius
Write a balanced chemical equation for this reaction. Express your answer as a chemical equation. Identify all of the phases in your answer.
Compute the pH for each of the following cases in the titration of 50.0 mL of 0.220 M HClO(aq) with 0.220 M KOH(aq).
How many micrograms are present in 2.3469 g? 1g= 1x10^6 micrograms. Please show your work and use significant figures in the answer.
Problem- A student starts with 2g of isopentyl alchol (MW =88) and 1.1mL of glacial acetic acid (Molecular weight = 60), density = 1.06 g per ml). 1) Calculate the limiting reagent
The half-life of 32P is 14.3 days. If you begin with 4.9 ?g (micrograms) of radioactive 32P in the form of Na2HPO4, what mass remains after 28.6 days (about one month)
Write out the balanced chemical equation that occurs when silver tarnishes in the presence of hydrogen sulfide ( a gas produced in food decay) and oxygen. Water is a by-product. Into which class of reactions does this reaction belong
How many total moles of ions are released when the following sample dissolves completely in water. 8.47x10^-2g of Ca(NO3)2
Problem- An alternative method to sanitizing pool water is to increase the salinity and pass an electric current through the water as it recirculates. Why would this be an effective treatment
