You want to make a buffer with a pH of 10.00 from NH4+/NH3.
(a) What must the [NH4+]/[NH3] ratio be?
(b) How many moles of NH4Cl must be added to 465 mL of an aqueous solution of 1.24 M NH3 to give this pH?
(c) How many milliliters of 0.236 M NH3 must be added to 2.08 g of NH4Cl to give this pH?
(d) What volume of 0.499 M NH3 must be added to 395 mL of 0.109 M NH4Cl to give this pH?
We need at least 10 more requests to produce the solution.
