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]
0.19 M barium hydroxide + 0.29 M barium bromide
0.28 M hydrobromic acid + 0.21 M potassium bromide
0.39 M potassium perchlorate + 0.24 M barium perchlorate
0.18 M nitrous acid + 0.13 M sodium nitrite
0.30 M ammonia + 0.39 M sodium hydroxide
