Answer : The solution with pH 8.3 is an alkaline solution.
Explanation: pH is a measure of hydrogen ion concentration; a measure of the acidity or alkalinity of a solution. The pH scale usually ranges from 0 to 14.
Aqueous solutions with a pH less than seven are acidic, acidity increases as the number decreases, 1 being the most acidic. Aqueous solution with a pH greater than seven are basic or alkaline, alkalinity increases as the number increases, 14 being the most alkaline. Aqueous solution with pH = 7.0 is a 'neutral' solution.
1) pH less than 7(pH < 7) , solution is acidic.

2) pH = 7 , solution is neutral.
3) pH greater than 7(pH > 7), solution is alkaline.

In our given question the pH of solution is given as 8.3 , since pH is greater than 7 , so the solution is 'Alkaline solution'.
