Complete the third row of the table.

Solution

We're being asked to complete the 3rd row of the missing pH, pOH, [H+], [OH-], acidic or basic in the table.

The pH and pOH of a compound determine its acidity or basicity.

  • pH 
    • pH stands for the negative logarithmic function of a hydronium ion concentration
    • can be calculated using the following equation:
