A buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. Its pH changes very little when a small amount of strong acid or base is added to it. A buffer is a special solution that stops massive changes in pH levels. Every buffer that is made has a certain buffer capacity, and buffer range.

This page describes simple acidic and alkaline buffer solutions and explains how they work.

What is a buffer solution? Acidic buffer solutions. An acidic buffer solution is simply . This tutorial presents a review of the definitions for pH and buffer solutions. Solutions able to retain a constant pH regardless of small amounts of acids or bases added are called buffers. Classical buffer contains both a weak acid and its conjugate base.

Small amounts of acids or bases added are absorbed by the buffer and the pH changes only slightly. In the case of high or low pH just solutions of .

Buffer solutions are used as a . The quality of your measurement depends upon the quality of your standards, buffers, and reagents. We offer a complete selection of quality- assured support solutions for virtually any electrochemistry analysis. Various pH buffer solutions for pH probe and meter calibration.

The pH of solutions is an important chemical property. Oxygen is much more electronegative than hydrogen. Both shared electrons in an oxygen-to-hydrogen bond tend to spend more time with the oxygen atom than with hydrogen. Although the vast majority of water molecules remain intact . We have pH buffer solutions, pH electrode storage solutions, electrode cleaning solutions, lab buffer kits, and electrode filling solutions for virtually every application.

Soil pH is the foundation of essentially all soil chemistry and nutrient reaction . Sealed foil pouches of pH buffers.
