Determine the titration of 50.00mL of a 0.100 M weak acid solution with 0.100 M NaOH. If the pH at the equivalence point is 5.0.
Explain what is the approximate buffer range for this system?
Treatment of ethyl isobutyrate with ethoxide in ethanol, followed by mild acidic workup, leads to recovery of starting material rather than a Claisen Condensation product. Please explain this observation, using structures rather than words as much..
burning 0.43g of the compound X (only contain C,H,O)in excess oxygen gives 1.10g of CO2 and 0.45g of H2O. what is the empirical formula?
mgnh4po4.6h2o loses h2o stepwise as it is heated. between 40c and 60c the monohydrate mgnh4po4.h2o is formed and above
where the temperature and pressure are 4oC and 3.0 atm, to the water's surface, where the temperature is 25oC and pressure is 0.95 atm. Calculate the final volume of the bubble if its initial volume was 2.1 mL
Calculate the grams of Titanium that will be plated from a Ti(NO3)4 solution using a current of 15 amperes for 3 hours
Can some one verbally explain the ideas of tunneling and reflection in the case of particles confronting an energy barier
Proteins are least soluble and often precipitate when the pH of the solution equals their pI. This property may be used to selectively permeate many other contaminating proteins, leaving the protein of interest in solution
