A 130.0 −mL buffer solution is 0.105 M in NH3 and 0.135 M in NH4BrNH4Br. The Kb value for NH3 is 1.76×10−5 Part A What mass of HCl can this buffer neutralize before the pH falls below 9.00? Part B If the same volume of the buffer were 0.265 M in NH3 and 0.390 M in NH4Br, what mass of HCl could be handled before the pH falls below 9.00? Express the mass in grams to three significant figures.
A 130.0 −mL buffer solution is 0.110 M in NH3 and 0.135 M in NH4Br. The Kb value for NH3 is 1.76×10−5. If the same volume of the buffer were 0.270 M in NH3 and 0.390 M in NH4Br, what mass of HCl could be handled before the pH falls below 9.00?
A 110.0 −mL buffer solution is 0.110 M in NH3 and 0.135 M in NH4Br. Part A: What mass of HCl can this buffer neutralize before the pH falls below 9.00? Correct Answer: 8.51x10-2 g Part B: If the same volume of the buffer were 0.255 M in NH3 and 0.395 M in NH4Br, what mass of HCl could be handled before the pH falls below 9.00? Express the mass in grams to three significant figures. Please help with Part B!...
A 130.0 −mL buffer solution is 0.100 M in NH3 and 0.135 M in NH4Br. What mass of HCl can this buffer neutralize before the pH falls below 9.00? Express the mass in grams to three significant figures. If the same volume of the buffer were 0.265 M in NH3 and 0.400 M in NH4Br, what mass of HCl could be handled before the pH falls below 9.00? Express the mass in grams to three significant figures.
For 490.0 mL of a buffer solution that is 0.125 M in HC2H3O2 and 0.110 Min NaC2H3O2, calculate the initial pH and the final pH after adding 0.010 mol of HCl. Express your answers using two decimal places separated by a comma.
