The most acidic solution has been solution C. The most basic solution has been solution b, and the least acidic solution has been solution A.
The given solutions in the compound has been:
Solution A = pOH = 1.5
Solution B = pOH = 7
Solution C = pOH = 13.5
The pH can be defined as the hydrogen ion concentration in the solution. The pH can be given as:
pH = 14 - pOH
pH = 14 - 1.5
pH = 12.5
The solution has thus been basic.
pH = 14 - 7
pH = 7.
The solution has been neutral.
pH = 14 - 13.5
pH = 0.5
The solution has been highly acidic.
The most acidic solution has been solution C. The most basic solution has been solution b, and the least acidic solution has been solution A, as it has been more basic thus least acidic.
