**A+ Solution

100% Correct

Question 1

A buffer solution is prepared by mixing 50.0 mL of 0.300 M NH3(aq) with 50.0 mL of 0.300 M NH4Cl(aq). The pKb of NH3 is 4.74. ph 14-4,74=9.26

7.50 mL of 0.125 M HCl is added to the 100.0 mL of the buffer solution. Calculate the new NH3 concentration for the buffer solution.?Calculate the new NH4Cl concentration for the buffer solution.?Calculate the new pH of the solution.

Question 2

A buffer solution is prepared by mixing 50.0 mL of 0.300 M NH3(aq) with 50.0 mL of 0.300 M NH4Cl(aq). The pKb of NH3 is 4.74.

7.50 mL of 0.125 M NaOH is added to the 100.0 mL of the original buffer solution prepared in Question 1 (no HCl added). Calculate the new NH3 concentration for the buffer solution.?Calculate the new NH4Cl concentration for the buffer solution.?Calculate the new pH of the solution.
