The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic.Click to see full answer. In respect to this, what does pH scale mean?A measure of acidity or alkalinity of water soluble substances (pH stands for ‘potential of Hydrogen’). A pH value is a number from 1 to 14, with 7 as the middle (neutral) point. Values below 7 indicate acidity which increases as the number decreases, 1 being the most acidic.Secondly, what is the strongest base on the pH scale? In technical words, the acid which dissociates completely into H+ ions in water will have the lowest pH value, while the base dissociates completely into OH- ions in water will have the highest pH value. EDIT : Strongest acid has pH of 1 while strongest base has pH of 14. (0 – 6.99 are acids. Also asked, why is the pH scale only up to 14? One can go somewhat below zero and somewhat above 14 in water, because the concentrations of hydronium ions or hydroxide ions can exceed one molar. The pH scale is limited on the low end by the highest concentration (activity) of [H+] in solution.What is pH formula?How to Calculate pH and [H+] The equilibrium equation yields the following formula for pH: pH = -log10[H+] [H+] = 10-pH. In other words, pH is the negative log of the molar hydrogen ion concentration or the molar hydrogen ion concentration equals 10 to the power of the negative pH value.
