To make tris acetate, you can mix tris base with acetic acid in a specific ratio and then adjust the pH level to achieve the desired tris acetate buffer solution.
The question is in poorly worded. I will assume the question is "why adjust the pH of Tris buffer with HCl and not Sodium Acetate?" I would assume the answer is - because sodium acetate is the conjugate base of a weak acid, and HCl is a strong acid. Also the salts you would be putting into the solution as a result would be different. I think the question is actually, "The pH of Tris is adjusted with HCl, why isn't the pH of sodium acetate adjusted with HCl?". I'm not sure of the answer exactly, but I've always assumed its because if you adjust the pH with glacial acetic acid instead of HCl, you won't introduce chloride ions.
To make 62.5 mM Tris-HCl solution, you would need to mix the appropriate amount of Tris base and HCl to achieve a final concentration of 62.5 mM. The calculation involves considering the molecular weights of Tris and HCl to determine the amount needed to make the desired concentration.
To prepare a 10mM solution of Tris-HCl, you would weigh out the appropriate amount of Tris-HCl powder using a balance and dissolve it in water to make a final volume of solution. For example, to make 1L of 10mM Tris-HCl solution, you would need to dissolve 0.121g of Tris-HCl in 1L of water.
Tris(hydroxymethyl)aminomethane (Tris) is a common buffer used in biochemistry, while Tris HCl is Tris buffer combined with hydrochloric acid to adjust the pH. Tris buffer is neutral (pH 7-9), while Tris HCl is acidic with a pH around 4.5-8.6.
TBE (Tris-borate-EDTA) buffer is used for nucleic acid electrophoresis and provides better resolution of larger DNA fragments, while TAE (Tris-acetate-EDTA) buffer is commonly used for agarose gel electrophoresis of DNA. The primary difference between the two buffers is the anion used (borate vs. acetate), which can affect the mobility of DNA fragments during electrophoresis.
0.04 M Tris-acetate, 0.001 M EDTA
DNA gels is a term that usually refers to agarose gels, made with TAE (Tris, Acetate, EDTA) or TBE (Tris, Borate, EDTA) buffer. They are the simplest to make and don't contain toxic compounds (unless EtBr is added to the gel).
The main difference is in composition. In TE common Tris buffer is bring down to pH 8 with HCl and EDTA is involved but in TAE instead of Tris HCl in TE Tris-acetate buffer is used.

To prepare 10mM Tris solution, first calculate the amount of Tris base needed based on the molecular weight of Tris (121.14 g/mol). Weigh out the appropriate amount of Tris base and dissolve it in water to make a final volume of 1L. Adjust the pH to the desired value if necessary.

To make a 1 mol tris buffer, you would need to dissolve 121.1 g of Tris (Tris(hydroxymethyl)aminomethane) in water and dilute to a final volume of 1 liter. Adjust the pH with a strong acid like HCl or a strong base like NaOH to reach the desired pH of the buffer.

yes
The formula weight is 121.5 --> this is equivalent to 1M with 121.5g tris in 1L dH20. For a 5M stock, use 5x as much tris in the same 1L dh20.607.5 g tris into 800ml dH2O - stirring - then pH to 7.5 with 6M HCl and QS to your final volume of 1L
