Question

A 120.0 ml. buffer solution 0.110 M NH3 and

0.135 M NH4Br. (Kb of NH3 is 1.76 x10^-5)

Part B

If the same volume of the butter were 0.265 M NH3 and 0.390 Min NH Br. What mass of HCl could be handled before the pH als below 9.00?

Express the mass in grams to three significant

Answer 1

Answer #1

& Oto) We use Henderson - Hasselbalch equation as legio ((NH4Br] + [H43) pOH = pkb + since ((NH3 ] - [HU]) POH 25 so that pH
