WebThe pH scale is a measure of acidity on a 14 point scale, where 7 is the neutral midpoint. pH is a logarithmic scale (like the Richter scale for earthquakes), so a pH of 4 is 10 times … WebHow acidic or basic a substance is can be measured on the pH scale. This is an inverse logarithmic scale from 1-14. A strong acid is a 1, 7 is neutral (a substance which is neither acidic or basic) and 14 is a strong base. The scale is a measure of the hydrogen ion (H +) and hydroxide ions (OH -) in the substance.
WebJan 30, 2024 · The pH scale is logarithmic, meaning that an increase or decrease of an integer value changes the concentration by a tenfold.

Introduction In aqueous solution, an acid is defined as any species that increases the concentration of \text {H}^+ (aq) H+(aq), while a base increases the concentration of \text {OH}^- (aq) OH−(aq).
WebNov 29, 2024 · The pH scale ranges from 0 to 14, with 0 indicating extremely acidic and 14 indicating extremely alkaline. If a pH value of 7 is found in any solution, it indicates that the solution is neutral in nature. Values less than 7 suggest an acidic solution, whereas values more than 7 indicate an alkaline solution.
