Sodium silicate serves as a builder in some detergents when used in high concentrations. When used in lower concentrations, it inhibits corrosion and adds crispness to detergent granules.
transport across the membrane
it act as as a cationic detergent for the isolation dna from the given sample
The actual role of phenol chloroform isoamyl alcohol in a plasmid DNA extraction is to purify the DNA. The alcohol will act in part as a detergent.
It stabilize the complex formed by the copper..
Electral is WHO based ORS (Oral Rehydration Solution) formula. The formula is basically a combination of Dextrose and a number of essential electrolytes like Sodium Chloride, Potassium Chloride, and Sodium Citrate. These electrolytes play a major role in conducting nervous impulses, contracting muscles, keeping you hydrated, and regulating your body's pH levels. Electral is used for the replacement of fluid and these electrolytes and maintenance of hydration in diarrhea, vomiting, and other conditions where there is a loss of water and electrolytes. Hence there is no difference between ORS and Electral powder.
In soap making, sodium silicate provides buffered alkalinity that suspends soil, or stains and waste matter. It helps clean surfaces by emulsifying or counteracting soil.
It has no inherent value in the cleaning capabilities of the laundry detergent.According to http://www.chemistry.co.nz/deterg_sundry.htm web site, sodium chloride plays the following role in detergents:Sodium Chloride NaClSalt is used as a viscosity increasing agent in anionic detergent solutions. Up to 10% salt can be added to a powder formulation and proves effective on blood, and on woollen garments. It has a positive effect on detergency.
The typical glass (a sodium and calcium silicate) result from the melting of silicon dioxide, sodium carbonate and calcium carbonate; sodium carbonate ia a chemical reactant here but also help to reduce the melting point of SiO2.
Sodium dodecyl sulphate is a surfactant and functions as a detergent. It solubilizes the lipids present in the cell membrane and internal membrane and components of cell and allows a DNA extract free from lipids which would otherwise be contaminants in biological and biochemical assays.
Salt, msg, baking soda and baking powder are the major providers of the mineral, sodium in our diets. Sodium plays a role in regulating fluids in and out of the cell and in our bodies. Sodium also helps transmit electrical signals in our brain, nervous system and our muscles. Sodium is excreted in the urine. Too much sodium in some people can increase blood pressure. An extremely high amount of sodium can lead to death.

In this case sodium chloride does not have any buffering role.
