Buffer, in chemistry, solution usually containing an acid and a base, or a salt, that tends to maintain a constant hydrogen ion concentration. Ions are atoms or molecules that have lost or gained one or more electrons. An example of a common buffer is a
Acid, any substance that in water solution tastes sour, changes the color of certain indicators (e.g., reddens blue litmus paper), reacts with some metals (e.g., iron) to liberate hydrogen, reacts with bases to form salts, and promotes certain chemical r
This paper presents a novel method for finding the pH of a solution containing a weak polyprotic acid(or base).The new method has the following characteristics:its constraint condition is simple,namely if a term is less than 5%of the maximum term among the polynomial,its contribution can be ...

Litmus or pH paper is filter paper that has been treated with a natural water-soluble dye so it can be used as a pH indicator, to test how much acid (acidity) or base (alkalinity) exists in a solution. You might have even used some to test whether the water in a swimming pool is...

What is an Acid? An acid is something that has a pH less than 7.0 . The chemistry definition of an acid is: "a substance that donates a hydrogen ion (H+) to another substance, which is called a base. (Or give out hydrogen ions when dissolved in water.)" ...
