Calculate the pH of a solution that is 0.200 M in NH3 and 0.300 M in NH4Cl. Calculate the pH
change that takes place when a 100-mL portion of (A) 0.0500 M NaOH and (B) 0.0500 M HCl is
added to 400 mL of the buffer solution. Kb = 1.75 x 10-5

1) Calculate the change in pH when 3.00ml of .1M HCl(aq) isadded to 100 ml of a buffer solution that is .1 M in NH3(aq) and.1M in NH4Cl(aq)

2)Calculate the change in pH when 3.0ml of .1 M NaOH (aq) isadded to the original buffer solution

Calculate the change in pH when 3.00 mL of0.100 M HCl(aq) is added to 100.0 mL of a buffer solution that is0.100 M in NH3(aq) and 0.100 M in NH4Cl(aq)? Calculate the change in pH when 3.00 mL of 0.100 M NaOH(aq) isadded to the original buffer solution?

Calculate the change in pH when 7.00 mL of 0.100 M HCl(aq) isadded to 100.0 mL of a buffer solution that is 0.100 M in NH3(aq)and 0.100 M in NH4Cl(aq).

... and then

Calculate the change in pH when 7.00 mL of 0.100 M NaOH(aq) isadded to the original buffer solution.
