Answer:
The pH os the substance is 1,92.
Explanation:
The pH is a measure that gives us an idea of the acidity or alkalinity of a solution. It is calculated as:
pH = -log (H +)= -log (1.2 x 10^-2 )=1,92
The pH scale ranges from values of 0 to 14 (less than 7.0 is acidic and greater than 7.0 is basic, a pH = 7.0 is neutral). In this case, the substance is acidic.
