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.
The pH of the substance is 1.92
pH & Hydrogen ion concentration
From the question, we are to determine the pH of the substance
The pH of the substance can be calculated by using the formula,
[tex]pH=-log_{10}[H^{+} ][/tex]
From the given information
[H⁺] = 1.2 × 10⁻² M = 0.012 M
Then,
[tex]pH=-log_{10}[0.012][/tex]
pH = 1.92
Hence, the pH of the substance is 1.92
