You have 100.0 mL of 0.100 M aqueous of each of the following acids: HCN, HF, HCl, and HC2H3O2. You titrate each with 0.100 M NaOH (aq). Rank the pHs of each of the solutions when each are titrated at the equilibrium point, from highest to lowest pH.
Ka for HCN = 6.2 10^-10
Ka fpr HF = 7.7 10^-4
Ka for ?HC2H3O2 = 1.8 10^-5
A room temperature aqueous solution is 0.10 M in zinc acetate, 0.50 M in strontium acetate and 15.2 M in nickel (II) acetate. At what concentration of carbonate does a solid first appear in the solution?
At body temperature (98.6F = 37.0C), Kw has the value 2.4X10^14. If the pH of blood is 7.4 under these conditions, what are the concentrations of H3O+ and OH-?
Calcutate the number of grams of drug to be wieghted for this solution
a solution of ethanol c2h5oh in water is prepared by dissolving 62.0 ml of ethanol density 0.79 gcm3 in enough water
The volume of the gas collected =500 ml then determine the mass of O 2 is collected? The vapor pressure of H 2 O at 25 degree Celsius =23.8 torr
Consider the decomposition of calcium carbonate. Assume that ?H° = 177.8 kJ/mol and ?S° = 160.5 J/K·mol for the temperature range. CaCO3(s) -> CaO(s) + CO2(g)
If the 3d and 4s bands overlap in a metal atom, what is the maximum number of electrons for this composite band
Determine the degree of unsaturation for C5H8. Draw constitutional isomers of C5H8 that are terminal and internal. Name each molecule according to IUPAC.
Predict the probability P9v) that a molecule will have a given total velocity of more specifically P(v)dv is the probability that a molecule will have a velocity btwn v and v+dv.
there are 4 catalysts and mechanisms. is there a pattern? what key intermediate would you observe for most of these catalysts? how are they significant?
Explain why a buffer made of equal concentrations of CH3COOH and CH3COO- does not change in pH when a small amount of NaOH (a strong base) is added to the solution. Does the NaOH dissociate into ions when it is added to the solution?
