1mM DPPH (MW 394.32) solution would be 0.39 mg/1mL
1M = 390 mg/1mL
To prepare a 1 mM DPPH radical solution, dissolve 3.94 mg of DPPH (2,2-diphenyl-1-picrylhydrazyl) in 1 liter of solvent (typically methanol or ethanol). This will result in a concentration of 1 mM (molecular weight of DPPH is approximately 394.3 g/mol).
To prepare a DPPH radical solution, dissolve DPPH powder in a solvent like methanol or ethanol to a concentration of around 0.1-0.2 mM. Mix well until the solution is completely dissolved. The solution can be stored in the dark and at low temperature to protect it from light.
a homogeneous solution MY ANSWER Uh...no! Its a solution! if u dont believe me, look up solution and there you go =) ...a homogenious solution?? WAYTT?? lol
a solution is a mixture as a solution is made only when two substances are mixed together so a solution is definitely a mixture!
it is a solution

To prepare a 0.2 millimolar (mM) DPPH solution in ethanol, you need to dissolve 0.2 millimoles of DPPH in a final volume of 1 liter of ethanol. First, calculate the molecular weight of DPPH (usually around 394.33 g/mol) to determine the mass needed to dissolve in ethanol. Then add this mass of DPPH to ethanol and make up the volume to 1 liter.
To store a DPPH in methanol solution for long-term purposes, it is recommended to seal the container tightly to prevent evaporation or contamination. Store the solution in a dark, cool place to minimize degradation of the DPPH. Periodically check the solution for any color changes or signs of degradation.
I really dont know people
Common reagents used in the estimation of antioxidants include DPPH (2,2-diphenyl-1-picrylhydrazyl) reagent, Folin-Ciocalteu reagent, and Trolox standard. These reagents are utilized in assays such as DPPH radical scavenging assay, total phenolic content assay, and oxygen radical absorbance capacity (ORAC) assay to measure the antioxidant capacity of compounds.

mixture or solution
optimal solution is the possible solution that we able to do something and feasible solution is the solution in which we can achieve best way of the solution
