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 solution that is resistant to change in pH?

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.

Where can someone find infromatuon about buffer solution?

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.


How do you elute DNA from filter paper?

Cut the piece of paper having the DNA into small pieces and drop it into a 1.5 mL microfuge tube. Add enough TE buffer to submerge the the piece of paper, give sufficient time for the DNA to get into the buffer. Spin the tube at 13,000 rpm for 5 minutes. collect the supernatant which has your DNA and use it Preetam,UWO


What is pseudo buffer?

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.


How do you calculate buffer in a chemical solution?

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.


What is a compound that minimizes changes in pH by reversibly taking up or releasing ions?

A buffer.


Effect of Diluting 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.


Does a buffer always hold the pH of a solution at pH 7?

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.
