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 solution - chemistryI have no idea where to start on this. Please give me a well-detailed explanation of how to solve this. Given: pKa; (CH3COOH) 4.75 pKa1 (H2SO3) = 1.90 pKa2 (H2SO3) = 7.20 Which of the following mixtures is (are) not a buffer mixture(s)? 1. A mixture...
Chemistry topics, they are buffer solution and solubility were chosen because these could explain phenomena in detail into microscopic aspect. This study aims to see student's attitude toward chemistry as part of scientific literacy after learning by coupled inquiry (CI) and guided inquiry (GI) ...

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
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 ...
The buffer capacity can be fixed controlling the total concentration of the acid in the final solution. Moreover, when choosing the most appropriate buffer to prepare a chromatographic mobile phase, it is necessary to take into account the kind of detector to be used. For example, UV-absorbing...

Why is HBr/KBr not a buffer solution? Give an example of a substance with a pH that is greater than 7. What does this tell you about the substance? 1. Very briefly, explain the difference between a buffered solution and an unbuffered solution in terms of changes to the pH when small...
