Noun1.buffer solution- a solution containing a buffer solution- a homogeneous mixture of two or more substances; frequently (but not necessarily) a liquid solution; "he used a solution of peroxide and water" buffer- (chemistry) an ionic compound that resists changes in its pH ...
In order to understand how a buffer works, consider the example of a buffer solution made by dissolving sodium acetate into acetic acid. Acetic acid is (as you can tell from the name) an acid: CH3COOH, while the sodium acetate dissociates in solution to yield the conjugate base, acetate i...
buffer solution Definition ofbuffer solution 1) Solution that resists change in pH; contains either a weak acid and a soluble ionic salt of the acid or a weak base and a soluble ionic salt of the base. Share & Recommend Tweet
1. To act as a buffer for or between. 2. Chemistry To treat (a solution) with a buffer. 3. Computers To hold or collect (data) in a buffer. [Probably from obsolete buff, to make a sound like a soft body being hit, of imitative origin.] American Heritage® Dictionary of the Eng...
Buffers are used to keep the pH of solutions within a specific range. The higher the amounts of HA and A–molecules in the buffer system, the less effect a strong base or acid has on the pH system. The capacity of a buffer to absorb a strong base or acid is determined by individua...
Forum: Chemistry T Buffer Solution Calculation Example Homework Statement Prepare a buffer solution of pH 3.746 from 25 mL of 0.244 M weak acid with pka 3.54 What volume, in mL, of 0.275 M NaOH would need to be added? I think that I have the answer but I am not sure, could you ...
Discover how the buffer system helps to prevent large changes in the pH of solutions. There are various buffer systems that exist in the body and...
pKa is the negative log of the acid dissociation constant or Ka value. A lower pKa value indicates a stronger acid. That is, the lower value indicates the acid more fully dissociates in water. pKa and Buffer Capacity In addition to using pKa to gauge the strength of an acid, it may be...
Chemistry has existed as long as humans have been around, although it has not always been a formal science like it is now. Even in prehistoric times, humans were recording known metals and materials. Aristotle in Ancient Greece declared the existence of four elements: water, air, earth, and...
