Can be mixed in a solution with H2CO3 to make a buffer?
H2CO3 is not used as buffer.
Why dont molecular compounds conduct electricity when dissolves in water?
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.
Is it possible to make a buffer of boric acid and borax?
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.
What is the purpose of salt in a buffer?
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.
How to make 1 mlar solution of bsa?
To make a 1 mg/mL solution of BSA (bovine serum albumin), weigh out 1 gram of BSA and dissolve it in a total volume of 1 liter of water or buffer solution. Make sure to mix well until the BSA is fully dissolved. This will give you a 1 mg/mL solution of BSA.
Is a buffer supposed to keep pH of a solution neutral?
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.
Can be mixed in a solution with H2CO3 to make a buffer?
H2CO3 is not used as buffer.
Can vinegar be used to make a buffer solution?
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.
How do you make buffer solution pH10?
See the link below.
How do you make this solution?
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?
What can be mixed in solution with H2CO3 to make a buffer?
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).
How do you make 1m kh2po4 buffer?
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.
How do you make urease solution?
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.
Does pH7 makes a solution neutral?
Yes it does make it neutral because 7 is in the middle! :D
How do you convert 1x buffer to 10x buffer?
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.
Why a buffer is used and the effects of a buffer on a solution?
A buffer is used to resist the change in pH when acid or alkali is added to a solution. This makes it a stable environment, eg. for enzymes. The buffer stops the pH of the solution changing too drastically.

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.
