Identify whether the mixing of each pair of solutions results in a buffer Check all that apply. The mixing of Check all that apply. 100.0 mL of 0.10 M NH3 and 70.0 mL of 0.15 MNH4Cl 50.0 mL of 0.10 MHCl and 35.0 mL of 0.150 MNaOH 125.0 mL of 0.17 MNH3 and 160.0 mL of 0.20 MNaOH 155.0 mL of 0.10 MNH3 and 150.0 mL of 0.11 MNaOH 50.0 mL of 0.20 MHF and 20.0 mL of 0.20 MNaOH will result in a buffer.

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
