ANATOMY

Detailed explanation-1: -pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic.

Detailed explanation-2: -If a solution has the lowest possible concentration of hydrogens, it will have pH of 14, since that is the lowest value that is possible in aqueous solution.

Detailed explanation-3: –An acidic solution has a pH less than 7; it has a high concentration of hydrogen ions.

Detailed explanation-4: -[H+]=10-7, which we call a pH of 7. In the same way, a solution with a pH of 5 contains 10-5mol/l of hydrogen ions, a solution with a pH of 6 contains 10-6mol/l of hydrogen ions, while the solution with a pH of 7 contains 10-7mol/l of hydrogen ions.

Detailed explanation-5: -On the pH scale, the number which has the highest concentration hydrogen ions is generally 0. This represents a solution with a hydrogen ion concentration of 1 mole per liter or 1 M.
