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 (check all that apply) initial type effect of change on pH change (check one) O pH higher o acidic basic O neutral o acidic H20 add KBr O pH lower O pH the same O pH higher O pH lower O pH the same O pH higher H20 basic add HBr neutral acidic basic add NaC104 | neutral acidic basic neutral pH lower O pH the same O pH higher OPH lower O pH the same DH20, HCIO add NaOH Explanation Check

Explanation / Answer

A)Water is neutral. when KBr is neutral salt when dissolved in water the PH remain same

B)Water is neutral and when HBr is added becomes acidic as HBr is acid.So the PH is lowered.

C)HClO4 in water is acidic and when NaClO4 ( salt that is formed from strong base and strong acid ) the PH of the solution is increased as it forms as strong base NaOH.

D) HClO4 in water is acidic and when NaOH is added it forms a salt NaClO4. so the PH is higher
