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 are charge neutral. Molecular compounds dissolve in water as individual molecules. For example if 1.0g of C12H22011 (sucrose or table sugar) dissolves in water the solid will become many individual C12H22011 molecules floating in water but will remain charge neutral. Therefore, this solution does not conduct electricity. This is known as a nonelectrolyte solution. On the other hand, when ionic compounds, like NaCl (table salt), are dissolved in solution they break up into individual ions. In this case Na+ and Cl-. These ions with their respective charges make the solution electrically conductive. This is called an electrolyte solution.
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.
A buffer is supposed to keep the pH of a solution from fluctuating too much. It helps keep the pH more-or-less consistent. Whether it keeps the solution neutral, it doesn't have to be neutral. You can make a solution be whatever pH you want, but different solutions and pHs require different approaches.
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).
Make Solution A by dissolving 174.18g of K2HPO4 in 1L of dH2O. Make solution B by dissolving 136g of KH2PO4 in 1L of dH2O. now mix solution A and B and finally adjust pH of your buffer.
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
The stocks are commonly labeled as X factors such as 10X, 5X, 100X etc. X-factor indicates that the solution is concentrated and must be diluted usually with water to 1X concentration for use. For eg: - A 100X concentrated solution should be diluted to 100 fold. to convert 1X to 10X take one ml of 1x buffer in a measuring cylinder and dilute it to make it 10 ml. its now 10x buffer.
