a. an ionic compound, usually a salt of a weak acid or base, added to a solution to resist changes in its acidity or alkalinity and thus stabilize its pH b. Also called: buffer solution a solution containing such a compound 4. (Computer Science) computing a memory device for temporarily...
When an acid and its conjugate base are present in solution together, that solution is said to be a buffer, since it may react with acid or base without significant changes in pH. A hydroponic nutrient solution contains several conjugate acid-base pairs, since there are so many species presen...

Substances like phenolphthalein are called acid-base indicators and they often are used for determining the approximate pH of solutions. Electrical measurements can determine the pH more precisely. The pH meter: Where rapid and accurate pH measurements are required, we use an instrument known as a...
6. the main ingredient of a mixture: to use rice as a base in cookery. 7. (Chemistry) a chemical compound that combines with an acid to form a salt and water. A solution of a base in water turns litmus paper blue, produces hydroxyl ions, and has a pH greater than 7. Bases are...
A buffer solution is a water-based solution with a stable pH. When a base is added to a buffer solution, the pH does not change. The buffer solution prevents the base from neutralizing the acid.
So you should specify problem more precisely. Buffer solution usually contain two reagents which are conjugated acid-base pairs according to Bronsted-Lowry theory. So, simple substitution cannot always work. Logged AWK Print Pages: [1]Go Up « previousnext »...
Buffer solutions are usually a combination of an acid and its conjugate base. As we learned above, acidity can be defined as the concentration of H+ ions in solution. Therefore, acids are compounds that release H+ ions into solution. If acids increase the concentration of H+, it follows th...
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
