The pH value is a measure of the acidity/basicity of a solution.
The pH scale is logarithmic, meaning each change of one unit represents a tenfold change in hydrogen ion concentration. For example, a change of 2 in pH corresponds to a 100-fold difference in hydrogen ion concentration. An increase in pH by 2 indicates a decrease in hydrogen ion concentration, while a decrease in pH by 2 indicates an increase in hydrogen ion concentration.
The indicator that gives you the range of colors for different pH numbers is called universal indicator. It is a mixture of several indicators that changes color over a wide pH range.
The pH scale is from 0 to 14. From 0 to 7 is acidic, and from 7 to 14 is basic. 7 is neutral. pH stands for "power of hydrogen".
The extreme points are now 0 and 14.
Oh, dude, a pH of 8 is definitely more basic than a pH of 6. It's like comparing a chill day at the beach to accidentally eating a spicy pepper. pH scale goes from 0 to 14, so 8 is closer to neutral (7) than 6, which is getting a bit acidic.
A pH under 7 is typical for acidic solutions.
The pH is under 1.
This pH is near 14.

pH numbers below 7 indicate an acid, with lower numbers indicating stronger acids. pH numbers above 7 indicate a base, with higher numbers indicating stronger bases.

pH values are indications of acidity/alkalinity of a solution.
Neutrality is a pH=7,00.
On the pH scale, acids have a pH of less than 7.
The pH number will determine if the liquid is acidic or alkaline.
The numbers 7.1 through 14 are the basic numbers.
