Get started for freeIn the Kjeldahl nitrogen determination, the final product is a solution ofin HCl solution. It is necessary to titrate the HCl without titrating.
(a) Calculate the pH of pure 0.010 M.
(b) Select an indicator that would allow you to titrate HCl but not.
Describe how you would prepare exactlyof picolinate buffer, . Possible starting materials are pure picolinic acid (pyridine-2-carboxylic acid, FM 123.11), 1.0 M HCl, and . Approximately how many milliliters of the orwill be required?
When you flip a coin, the probability of its landing on each side isin Equations 28-2 and 28-3. If you flip it times, the expected number of heads equals the expected number of tailsThe expected standard deviation for flips is. From Table 4-1, we expect thatof the results will lie withinand of the results will lie within.
(a) Find the expected standard deviation for the number of heads incoin flips.
(b) By interpolation in Table 4-1, find the value of that includesof the area of the Gaussian curve. We expect thatof the results will lie within this number of standard deviations from the mean.
(c) If you repeat thecoin flips many times, what is the expected range for the number of heads that includesof the results? (For example, your answer might be, "The rangetowill be observedof the time.")
Theof microscopic vesicles (compartments) in living cells can be estimated by infusing an indicator (HIn) into the compartment and measuring the quotientfrom the spectrum of the indicator inside the vesicle. Explain how this tells us the.
To pre-concentrate cocaine and benzoylecgonine from river water described at the opening of this chapter, solid-phase extraction was carried out at using the mixed-mode cation-exchange resin in Figure 28-19. After passing of river water through of resin, the retained analytes were eluted first with of and then with ammonia solution in
. Explain the purpose of using
for retention and dilute ammonia for elution.
