potassium acetate (KAc) is added, which does three things:
a. Circular DNA is allowed to renature. Sheared cellular DNA remains denatured as single stranded DNA (ssDNA).
b. The ssDNA is precipitated, since large ssDNA molecules are insoluble in high salt.
c. Adding sodium acetate to the SDS forms KDS, which is insoluble. This will allow for the easy removal of the SDS from your plasmid DNA.
For DNA to precipitate down when ethanol added it needs a higher salt concentration which will allow it to precipitate more accurately, hence this salt is given in form of Na acetate which is the best salt for the purpose or else NaCl
Sodium acetate is added during DNA extraction to help precipitate the DNA by neutralizing the electric charge on the DNA molecules. This allows the DNA to aggregate together and be easily separated from other cellular components. Additionally, sodium acetate helps to create the optimal conditions for the DNA to form a stable precipitate when mixed with alcohol.
Sodium chloride help to separate DNA from other proteins.
The sodium acetate disrupts the solvent shell created by the water; which is what makes DNA soluble in water. So as you could imagine, if the solvent shell is disrupted the DNA precipitates out.
Ammonium acetate is used in DNA extraction to precipitate DNA from solution. It helps to neutralize the pH of the solution and allows DNA molecules to form a complex with the acetate ions, leading to DNA precipitation. This facilitates the separation of DNA from other cellular components.
Sodium acetate is used in DNA isolation as a salt to promote DNA precipitation, helping to remove contaminants and impurities from the DNA sample. It is commonly used in combination with ethanol to precipitate DNA from solution, allowing for the extraction and purification of DNA for further analysis. Sodium acetate also helps to maintain the appropriate pH level for DNA precipitation to occur effectively.

Sodium acetate is used in DNA extraction to precipitate out proteins and other contaminants. By adding sodium acetate to the DNA sample, it creates a high-salt environment which helps DNA molecules come out of solution and form a visible pellet, making it easier to separate from the rest of the sample. This purification step ensures a higher yield and purity of extracted DNA.

Sodium citrate is used in DNA isolation to prevent DNA degradation by chelating divalent cations such as magnesium and calcium, which can act as cofactors for DNases. By binding these ions, sodium citrate helps to stabilize the DNA and protect it from enzymatic degradation during the isolation process.
NaCl provides Na+ions which form ionic bond with the negatively charged phosphate of DNA,thus neutralizing the effect of negative ,negative repulsion of DNA and helps the DNA molecules to come closer and compact to simplify our process of DNA isolation...

Mercapotoethanol is used as an antioxidant. Especially for polyphenolics which become insoluble when oxidised and tend to precipitate with the DNA. Sodium sulphite (1.2 g/L) does the same thing without the stink.
