They are all basically the same thing. Tris-HCl is just the Tris base converted to a salt with HCl. You can buy either one. The advantage of starting with powdered Tris-HCl is that it is more soluble in water than the base and as a solution has a more neutral pH which is usually the desirable buffer point. Tris base has a pKa of over 8 so using Tris-HCl saves you the trouble of bringing it to a more neutral pH. The one thing to be careful of when making solutions from powder is to be sure to use the correct molecular weight which differs between the two.

To answer your specific question, it doesn't matter which you start with except in the rare cases where the sodium from the NaOH would be an issue. For your situation where the solution is going to be slightly basic, it sounds like you could use either one as the starting reagent. I would go with whatever is already around the lab.

What is the difference between tris tris cl and tris hcl?

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.


What is the difference between TAE buffer and TE buffer?

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.


How do you prepare 10mM solution of Tris-HCl?

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.


How do you prepare 10mM Tris Hcl?

1.21 g Tris-HCl, QS water to 1L. Scale appropriately.


What ia the role of tris-hcl in DNA isolaition of plant?

What is the buffer capacity of Tris HCl?

The buffer capacity of Tris HCl depends on its concentration and the pH range of interest. Typically, Tris HCl has a good buffering capacity around its pKa value of approximately 8.1. At this pH, Tris HCl can resist changes in pH when small amounts of acid or base are added.


What is Tris HCl?

"Tris" is a chemical compound used as a buffer. The full name is tris(hydroxymethyl)aminomethane. Tris has the ability to absorb counter ions (+H and -OH) so as to help keep the solution that they are in at a stable pH level. When the pH of Tris is set using HCl (hydrochloric acid) the buffer is called Tris HCl.


How do you prepare 0.1M tris HCl?

To prepare 0.1M Tris-HCl, dissolve 1.21 g of Tris (molecular weight 121.14 g/mol) in distilled water to make 100 mL of solution. Adjust the pH to 7.4 using HCl.


How do you make 62.5 mM Tris-HCl?

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.


How do you prepare 0.5M Tris-HCL pH 7.2?

To prepare 0.5M Tris-HCl pH 7.2, first calculate the amount of Tris base needed using the molecular weight of Tris (121.14 g/mol). Then dissolve the calculated amount of Tris base in water, adjust the pH to 7.2 using HCl while monitoring with a pH meter, and make up the final volume.


How make tris hcl?

To prepare Tris hydrochloride (Tris HCl) solution, dissolve Tris base in water to the desired concentration, then add hydrochloric acid (HCl) dropwise while monitoring the pH to achieve the desired pH level (usually around pH 7.0-8.0). Ensure safety precautions are followed when handling acids.


What Volume of 5M HCl to make tris buffer at pH 7.5?

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
