In general, a buffer system can be represented by writing a salt followed by slash and an acid or conjugate base followed by slash and an acid like salt/acid or conjugate base/acid. Thus, the sodium acetate-acetic acid buffer system can be written as
CH3COONa/ CH3COOH or CH3COO-/CH3COOH
Similarly, ammonia-ammonium chloride buffer system can be represented as
NH3 / NH4+
Note that NH4+ is an acid and NH3 is a conjugate base according to Lewry-Bronsted concept.
H2CO3 is not used as buffer.
There are many places where one can find information about buffer solution. One can find information about buffer solution at popular on the web sources such as Chem Guide and Doc Brown.
A buffer.
When acid is added to a buffer solution at pH 7, the pH of the buffer solution will decrease. However, due to the presence of a conjugate base in the buffer solution, the buffer will resist the change in pH and try to maintain its original pH value. This is because the conjugate base will react with the acid and prevent a significant decrease in pH.
The paper sank in the buffer solution because paper is denser than the liquid in the buffer solution. The density of the paper caused it to displace an equal volume of liquid, resulting in the paper sinking rather than floating.
A buffer solution is resistant to changes in pH because it contains a weak acid and its conjugate base, which can react with added acid or base to maintain a relatively constant pH. Buffers are commonly used in biochemical and chemical systems to prevent drastic changes in pH levels.
tris, EDTA (TE solution) and NaCl, TNE buffer is a buffer solution used in molecular biology, especially for DNA and RNA
Buffer Resist and Maintains the PH of the solution if there change in the environment of the solution.

A pseudo buffer is a theoretical construct used in computer science to explain certain algorithms or data structures. It is not an actual buffering mechanism, but a conceptual idea to simplify the explanation of complex systems.
To calculate the buffer capacity of a chemical solution, you can use the formula: Buffer capacity (moles of added acid or base) / (change in pH). This formula helps determine the ability of a buffer solution to resist changes in pH when an acid or base is added.
A buffer.
The buffer capacity increases as the concentration of the buffer solution increases and is a maximum when the pH is equal to the same value as the pKa of the weak acid in the buffer. A buffer solution is a good buffer in the pH range that is + or - 1 pH unit of the pKa. Beyond that, buffering capacity is minimal.
No, a buffer does not always hold the pH of a solution at pH 7. A buffer is a solution that can resist changes in pH when an acid or base is added. The actual pH at which a buffer solution can effectively resist changes depends on the specific components and their concentrations in the buffer system.
When acid is added to a buffer solution at pH 7, the pH of the buffer solution will decrease. However, due to the presence of a conjugate base in the buffer solution, the buffer will resist the change in pH and try to maintain its original pH value. This is because the conjugate base will react with the acid and prevent a significant decrease in pH.
