Question

Each row of 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. | solution | initial components | initial type (check all that apply) | change | effect of change on pH (check one) | | :---: | :---: | :---: | :---: | :---: | | A | H?O | ? acidic ? basic ? neutral | add KNO? | ? pH higher ? pH lower ? pH the same | | B | H?O, HI | ? acidic ? basic ? neutral | add NaOH | ? pH higher ? pH lower ? pH the same | | C | H?O | ? acidic ? basic ? neutral | add HNO? | ? pH higher ? pH lower ? pH the same | | D | H?O, HI | ? acidic ? basic ? neutral | add NaI | ? pH higher ? pH lower ? pH the same |
