Answer : The correct option is, (B) Acidity
Explanation :
pH : It is defined as the negative logarithm of the hydrogen ion or hydronium ion concentration.
Mathematically, it is represented as,
[tex]pH=-\log [H^+][/tex]
pH of the solution measures the acidity and basicity of a substance.
The pH range for acidic solution is, 0.1 to 6.9
The pH range for basic solution is, 7.1 to 14
For neutral solution the pH is, 7
Hence, the pH of solution measure the acidity.
