What is the full form of pH?
Answer
pH stands for potential of Hydrogen (also read as power of Hydrogen), a measure of the H⁺ ion concentration in a solution.
The working
Expand the term
The p stands for potenz or potential (power), and H stands for Hydrogen ion. So pH means the potential of Hydrogen ion.
What it measures
It indicates how acidic or basic a solution is by measuring the concentration of H⁺ (hydrogen) ions present.
Mathematical meaning
pH is defined as the negative logarithm of hydrogen ion concentration, pH = -log[H⁺].
Why it matters
A lower pH means more H⁺ ions and higher acidity, while a higher pH means fewer H⁺ ions and higher basicity.
