Establish the proper buffer pairs and analyze each choice if they are possible buffer pair
Step 1. Recall that buffers resist drastic changes to the pH if a strong acid or strong base is added.
A buffer is a solution that can be made up of:
Which of the following aqueous solutions are good buffer systems? [YOU CAN PICK MORE THAN ONE]
0.36 M calcium perchlorate + 0.20 M potassium perchlorate.
0.31 M ammonia + 0.36 M ammonium nitrate.
0.21 M nitric acid + 0.16 M sodium nitrate.
0.16 M barium hydroxide + 0.29 M barium chloride.
0.11 M hydrofluoric acid + 0.17 M perchloric acid.
