If the concentration of EDTA in the blood of a patient is 2.45x10^-8 M and the formation constant for the complex, [Pb(EDTA)]^-2 is 2.00x10^18, what is the concentration ratio of the free (and potentially toxic) Pb^2+ (aq) in the blood to the much less toxic Pb^2+ -EDTA complex?
An increase in the temperature of the reactants causes an increase in the rate of reaction. The best explanation for this behavior is that as the temperature increases
A 30.0-mL sample of 0.165 M propanoic acid is titrated with .300 M KOH. Calculate the pH after the following amounts of base is added
A chemist must dilute 80.5mL of 126mM aqueous sodium thiosulfate solution until the concentration falls to 110.mM . He'll do this by adding distilled water to the solution until it reaches a certain final volume.
the volume of NaOH needed to neutralize it and repeats the process several times to determine the concentration of the NaOH solution. She calculates the concentration and uncertainty in the concentration of the NaOH from the titration data.
For the table below, write which orbital goes with the quantum numbers. Don't worry about x, y, z subscripts. If the quantum numbers are not allowed, write "not allowed."
Hydrogen chloride gas can be prepared by the following reaction: 2NaCl(s)+H2SO4(aq) 2HCl(g)+Na2SO4(s) How many grams of HCl can be prepared from 2.00 mol H2SO4 and 150g NaCl.
