|
False
|
|
|
Either A or B
|
|
|
None of the above

Explanation:
Detailed explanation-1: -The pH scale is used to rank solutions in terms of how acidic or how basic they are. It indicates the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in a solution. These ion concentrations are equal in pure water, which has a pH of 7.
Detailed explanation-2: -The value of pH is inversely related to the concentration of hydrogen ions. Hence, higher is the hydronium ion concentration, lower will be the pH value.
