Answer:
The pH of the solution is 1.34, being an acidic pH.
Explanation:
pH is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.
The acronym pH stands for hydrogen potential.
The pH scale ranges from 0 to 14. Values less than 7 indicate the acidity range and those greater than 7 indicate alkalinity or basicity. Value 7 is considered neutral. Mathematically, pH is the negative logarithm of the molar concentration of hydrogen or proton ions (H⁺) or hydronium ions (H₃O⁺).
pH= - log [H⁺] = - log [H₃O⁺]
In this case, [H⁺]= 4.6*10⁻² M. Replacing:
pH= - log 4.6*10⁻²
Solving:
pH= 1.34
