Which of the following aqueous solutions are good buffer systems? . 0.24 M hydrochloric acid + 0.23 M sodium chloride 0.28 M ammonia + 0.35 M ammonium nitrate 0.16 M barium hydroxide + 0.28 M barium bromide 0.15 M nitrous acid + 0.14 M potassium nitrite 0.35 M calcium nitrate + 0.21 M calcium iodide

The aqueous solutions that are good buffer systems are:

We want to determine which of the given solutions would make a good buffer.

A buffer is a solution used to resist abrupt changes in pH when an acid or a base is added.

Which of the following aqueous solutions are good buffer systems?

The aqueous solutions that are good buffer systems are:

0.28 M ammonia + 0.35 M ammonium nitrate and 0.15 M nitrous acid + 0.14 M potassium nitrite

Explanation:

Buffer solution is the solution which resists the change in the magnitude of the pH when small additions of either acid or base is added.  

Acidic Buffer solutions consist of weak acid and its conjugate base usually mixed in relatively equal and large quantities.

Basic Buffer solutions consist of weak base and its conjugate acid usually mixed in relatively equal and large quantities.

Thus 0.28 M ammonia + 0.35 M ammonium nitrate ( weak base + conjugate acid)  and 0.15 M nitrous acid + 0.14 M potassium nitrite (weak acid + conjugate base)  are good buffer systems

jjj89t'ji; it hink the answer is your mom is not si

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
