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 | H2O | acidic basic neutral | add NaNO3 | pH higher pH lower pH the same | | B | H2O, HBr | acidic basic neutral | add KBr | pH higher pH lower pH the same | | C | H2O | acidic basic neutral | add HNO3 | pH higher pH lower pH the same | | D | H2O, HBr | acidic basic neutral | add KOH | pH higher pH lower pH the same |
