Each row or the table below describes an aqueous solution at 25 °C. The second column of the table shows the initial components of the solution. • Use the checkboxes in the third column to explain the type of the initial solution. The fourth column describes a change in the solution. • Use the fifth column to predict how the change in the solution will change its pH. dlo initial type (check all that apply) effect of change on pH (check one) solution initial components change O acidic рH higher H,0, HI add Nal A basic pH lower neutral pH the same acidic pH higher B H,0 basic add K Br pH lower neutral pH the same acidic рH higher H,0 basic add KOH pH lower neutral pH the same acidic рH higher H,0, HI D basic add Na OH pH lower neutral pH the same O OO O OO O O O O
