For the preparation of a solution with the pH=7,00:
Add 29,1 mL sodium hydroxide solution 0,1 M to 50 mL potassium dihydrogen phosphate solution 0,1 M.
H2CO3 is not used as buffer.
Molecular compounds do not conduct electricity when dissolved in water because they do not dissociate into ions. Ionic compounds dissociate into ions in water, which allows them to carry an electric current. Since molecular compounds do not break apart into ions, they do not have the ability to conduct electricity in water.
Yes, it is possible to make a buffer solution using boric acid and borax. Boric acid and borax can act as a buffer system when mixed in the right proportions, typically in a weakly acidic pH range around their pKa values. This buffer system would be appropriate for specific applications where this particular pH range is desired.
Salt in a buffer helps to maintain a constant ionic strength, which can affect the stability and effectiveness of the buffer solution. It also helps to minimize changes in pH that may occur due to dilution or added components.
Equilibrated phenol is phenol that has been mixed with an appropriate buffer solution to maintain a specific pH. This helps to stabilize the phenol solution and make it suitable for various biological applications, such as DNA extraction and purification.
Buffers help to maintain the pH of a solution within a specific range by resisting changes in pH when acids or bases are added. However, buffers are not necessarily designed to keep the pH neutral; rather, they stabilize the pH at a certain value depending on the components of the buffer solution.
H2CO3 is not used as buffer.
No, vinegar cannot be used to make a buffer solution. A buffer solution typically consists of a weak acid and its conjugate base, such as acetic acid and sodium acetate. Vinegar is a dilute solution of acetic acid only and lacks the necessary components to act as a buffer.

I don't know how to make the solution below. Low salt buffer: 10 mM phosphate buffer, 10 mM NaCl, pH 7.4. Could you tell me the method in detail?
A weak acid or its conjugate base can be mixed in solution with H2CO3 to make a buffer. Suitable options could be sodium bicarbonate (NaHCO3) or a weak acid like acetic acid (CH3COOH).
To make a 1M KH2PO4 buffer solution, dissolve 136.09 grams of KH2PO4 in enough water to make a final volume of 1 liter. Always ensure that the pH of the solution is adjusted to your desired value using an appropriate acid or base, such as NaOH or HCl.
To make a urease solution, simply dissolve urease enzyme powder in an appropriate buffer solution of your choice, such as phosphate buffer at the desired pH. The concentration of urease in the solution will depend on the specific experiment or assay you are conducting, so adjust the concentration as needed. Remember to keep the solution cold and handle the enzyme with care to maintain its activity.
To make a buffer solution, mix a weak acid and its conjugate base or a weak base and its conjugate acid in a specific ratio. This helps maintain a stable pH level when small amounts of acid or base are added.
To make lysis buffer, mix a detergent like SDS or Triton X-100 with a buffer solution like Tris-HCl. Adjust the pH to around 7.4 and add protease inhibitors if needed. This solution helps break open cells and release their contents for further analysis.
Yes it does make it neutral because 7 is in the middle! :D
To convert 1x buffer to 10x buffer, you would dilute the 1x buffer solution by adding 9 parts of a suitable solvent (such as water) to 1 part of the original buffer solution. This dilution will result in a 10x concentration of the buffer.
