How many grams of glycine amide should be added to 1.00 g of glycine amide hydrochloride to give 100 mL of solution with pH 8.00?

50mL of a 2.0M HCl solution is diluted to 6,000mL with distilled water. what is the pH of the resulting solution?

An analytical chemist is titrating 221.9 mL of a 0.8100M Solution of diethylamine ((C,H3),NH) with a 0.7200M Solution of The pK, of diethylamine is 2.89. Calculate the pH of the base solution after the chemist has added 131.7 mL of the HNO, solution to it. HNO3. 2 Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HNO, solution added. Round your answer to 2 decimal places. pH = U

You have chosen Methylamine as your weak base in the buffer solution. You have already added enough of the conjugate acid salt to make the buffer solution concentration at 0.48 M in this salt. The desired pH of the buffer should be equal to 9.75. To prepare the buffer, a total volume of 550 mL is required. The stock solution of the weak base is available at 1 gallon with a concentration of 0.98 M. (Remember the lesson on dilution: C1V1=C2V2) 4. How many mL should be taken from the stock solution to prepare the desired buffer solution? (round off final answer to 1 decimal place)

An analytical chemist is titrating 106.0 mL of a 0.1800M solution of piperidine (C5H₁NH) with a 0.7800M solution of HIO3. The pK, of piperidine is 2.89. Calculate the pH of the base solution after the chemist has added 15.4 mL of the HIO3 solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HIO3 solution added. Round your answer to 2 decimal places. pH = X B Ar

Azelastine hydrochloride (pKa = 8.88, molar mass = 418.36 g mol-1) is an antihistamine used in nasal sprays to treat seasonal allergies, like hay fever. What is the pH of a 30.0 mL aqueous solution with 45.0 mg of azelastine hydrochloride?a.  5.66b.  4.35 c.  8.34d.  3.78e. 10.22

Quinine (C20 H24 N2O2) is the most important alkaloid derived from cinchona bark. It is used as an antimalarial drug. For quinine, pKb, = 5.1 and pK, = 9.7 (pK, = - log Kp). Only 1 g quinine will dissolve in 1930.0 mL of solution. Calculate the pH of a saturated aqueous solution of quinine. Consider only the reaction Q+ H20 = QH+ + OH° described by pK,, where Q = quinine. pH =

How many mL of 0.2016 M KOH would be expected to be used in the titration of 0.3266 g of a diprotic acid with a molar mass of 62 g/mole?
