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 A B C H₂O H₂O, HNO3 H₂O H₂O, HNO3 initial type (check all that apply) acidic basic neutral acidic basic neutral acidic basic neutral acidic basic neutral U change add NaOH add KNO3 add NaCl add KOH effect of change on pH (check one) pH higher pH lower pH the same pH higher pH lower pH the same pH higher pH lower pH the same pH higher O pH lower O pH the same
