A chaotropic salt is a salt that disrupts stabilizing intra-molecular forces such as hydrogen bonding. They the structures of biomolecules as proteins and nucleic acids.
It will make hydrophobic proteins more soluble in water.
Examples: magnesium chloride, lithium acetate, lithium perchlorate.

What happens to DNA in the presence of a chaotropic salt?
The term "chaotropic" means chaos-forming, a term which in biochemistry usually refers to a compound's ability to disrupt the regular hydrogen bond structures in water. Hydrogen bonding profoundly affects the secondary structure of polymers such as DNA, RNA, and proteins, as well as how water-soluble a molecule is. Under native conditions, nucleic acids are covered by a hydrate shell consisting of water molecules that maintain the solubility of DNA in aqueous solutions. With the addition of chaotropic ions to the nucleic acid, this relatively ordered structure of water molecules of the hydrate shell is destroyed. The chaotropic salts create a hydrophobic environment. Under these hydrophobic conditions, the silica membrane of the NucleoSpin columns is the most suitable binding partner for the nucleic acids. Proteins, metabolites, and other contaminants do not bind to the membrane and therefore are washed away during the subsequent washing steps. As a further feature of the chaotropic salts, the respective cations saturate the silica membrane with positive charges, which still improves the binding of nucleic acids under hydrophobic conditions. Chaotropic salts increase the solubility of nonpolar substances in water. They denature proteins because they have the ability to disrupt hydrophobic interactions. They do not denature DNA or RNA. Their function in the NucleoSpin Extraction Kit is to denature cellular proteins (such as DNase and RNase). The high concentration of salt also facilitates binding of the nucleic acids DNA and RNA to the silica membrane in the column.
What product of an acid-base reaction is an ionic compound?

Is bitter salt sea salt?
Sea salt is sodium chloride, bitter salt is Epsom salt (magnesium sulfate heptahydrate).
Is salt in a salt solution is solvent or solute?
Solute, because it is the minor component in the solution and it is what dissolves in the solvent. For example: Salt Water - The salt is the solute that dissoles in the solvent, which is water.
Which word best describes the salt?
An adjective is a word that best describes the salt; for example much salt, little salt, or some salt.
How do you say chaotropic salt in french?
chaotropic isn't a word.
Why sodium iodide for DNA elution?
its used as its a chaotropic salt..dat is it melts the agarose piece containing the DNA fragment when incubated at 45-55 degress Celsius
Definition d'agent chaotropique?
Those are apparently the French words for "chaotropic agent." Here is the definition of "chaotropic agent": An agent that disorganizes the structure of water and can denature proteins by disrupting hydrophobic interactions. www.nature.com/nrn/journal/v3/n8/glossary/nrn898_glossary.html -

What solvent dissolves silk?
6M Lithium Bromide, or another harsh chaotropic agent.
What is the role of urea in DNA extraction?
Urea is a chaotropic agent, and its role is obviously denature proteins and DNA, and promote more stability to the system, breaking the hydrogen ligations between DNA and water and making the intramolecular ones more stronger.
Is the salt water actually salt?

acidic salt basic salt normal salt
What are the ingredients in Rock Salt?
Salt. Nothing else added. Salt is a crystal and rock salt is salt that is not made into a fine grained salt.
In salt water the salt is?
the salt is the solute
