What is the functional group of citral?
The functional group of citral is the aldehyde (alkanal) group. It has the structure -CHO
Citral reacts with bromine dissolved in water?
Citral reacts with bromine dissolved in water to form a dibrominated product. This reaction involves the addition of bromine across the carbon-carbon double bond in the citral molecule. Dibrominated citral is formed as a result of this halogenation reaction.
Why KCl or KF is added in the electrolysis of molten NaCl?
To decrease melting point of NaCl
Why NaOH and HCL were added in liquid-liquid extraction experiment and please write the equation?
NaOH was added to convert the acidic component into its conjugate base, making it water-soluble and enabling its extraction into the aqueous phase. HCl was then added to neutralize the basic component and convert it back into its neutral form, making it extractable into the organic phase. Equation: HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)
What does NaCl do during protein extraction?
In solution, NaCl can split into Na+ and Cl- ions. These ions are indeed needed to stabilise the hydrophilic residues of the protein molecule that are exposed on the surface. So NaCl is a stabilising agent in various protocols even in the extraction, but it does not has any role in lysing the cells or neutralising other biomolecules.
Why is NaCl extracted with water three times as opposed to only once?
Extracting NaCl with water three times helps to ensure that as much NaCl as possible is extracted from the solid material. Each extraction helps to increase the efficiency of separating NaCl from impurities or other soluble components. By repeating the process multiple times, the overall yield of NaCl is increased, resulting in a purer final product.
Is there a difference netween citric acid and citral acid?
does citric acid occur only in the fleshy fruit or is it found in citral
Is NaCl plus H2O a mixture?
Yes. When NaCl is added to water, it forms a solution, which is a homogeneous mixture.
What would be observed when NaCl is added to water?
When NaCl is added to water, the NaCl crystals dissolve and dissociate into Na+ and Cl- ions. This creates an electrolyte solution where the ions are free to move around in the water. The solution may also experience a temperature change due to the dissolution process.
Can klebsiella pneumonaie grow in NaCl 5.5?
yes, in BHI (brain heart infusion) medium with added NaCl.
What was the purpose of adding nacl to the distillate before extraction with methylene chloride?
Adding NaCl (sodium chloride) to the distillate before extraction with methylene chloride serves to enhance the separation of organic compounds from aqueous solutions. The addition of NaCl increases the ionic strength of the solution, which promotes the "salting out" effect, helping to reduce the solubility of organic compounds in water. This leads to a more efficient extraction of the desired compounds into the organic solvent, methylene chloride, thereby improving the yield and purity of the extracted substances.
