Answer : The number represents a basic pH is, 9
Explanation :
pH : It is defined as the negative logarithm of hydrogen ion and hydronium ion concentration.
The pH range is, 1 to 14.
When the value of pH is less than 7 then the solution is acidic.
When the value of pH is more than 7 then the solution is basic.
When the value of pH is equal to 7 then the solution is neutral.
From the given information we conclude that, the pH = 4 is an acidic because the value of pH is less than 7 and pH = 9 is a basic because the value of pH is more than 7.
Hence, the number represents a basic pH is, 9
