Answer : The correct option is, Basic.
Explanation :
pH : It is defined as the negative logarithm of hydrogen ion or hydronium ion concentration.
[tex]pH=-\log [H^+][/tex]
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.
As per question, an unknown solution has a pH of 8 that means the pH is more than 7. So, the solution will be basic in nature.
Hence, this solution is basic in nature.
