5. What is the effect of pH on organic bases (RN) an LLE? es (RN) and how does it affect their separation in 6. What is the effect of pH on neutral organ in LLE? on neutral organic compounds and how does it affect their separation 1. Draw a simple liquid-liquid extraction setup. Make sure you label all components of the setup including the two phases. 6. Illustrate a simple separation process of two solutes (a hydrophilic and a hydrophobic) using LLE

Answer 1

vent thod to separate on their selative organic bases (R ) and o what is the effect of pH on a How does it affect their separation in LLE & Stoliquid - Liquid extraction (LLE), also known as a extraction ond partitioning is a method to sen compounds or metal complexes, based on their a solubilities in two diffrent immiscible liquids, usuall water (polar) and on organic solvent cnon-polar) - There are two terms used for describing this out distribution, one of which how to do this separatione relates to the effect that pH will have on the orgonic bases (R3N) ③ The analogous unsupported organic phase but est scarcely affects the actual distribution coefficient of a metal, What is the effect of PH on neutral organic compound and how does it affect their separation in LLE? Neutral compounds do not react with either Bronsted acids or boses to achieve Separation, this strategy is coupled with the liquid liquid extraction method, in which a solute is transferred from one solvent into another. 4024 Neutral compounds that are neither acid nor i base and have a pH op of include number one Pure water or H2o. ② Draw a simple liquid liquid extraition setup, make sure you label all components of the setup including the two phases. o Liquid-liquid extraction (LIE), also known as solvent extraction and partitioning, is a method to Seporate compounds or metal. - The Stopper has to be semoved when droining the lower layer. 0 242 +27 if the stoppen were not Scanned with CamScanner semoved, a vaccum.

will build up above the liquid upon droining. This vaccum will seduce the rate of dranining and ultimately stop ito completely 3 After some time, the vaccum will suck air in (from the stem). @ the phases will mix again, Start y post-reaction mixture is mixture added quenched by water to seperatory funnel. Rinse with organic solvent and/or water -is reaction flask coldered in sesidue * Extract, & allow phases to seperate phase 2 4 Seperate the organic layer from the ageous Illustrate a simple separation proccess of two solutes cahydrophilic on a hydrophobic) using LLE. for separation and purification of proteins in pilot scale aqueous two-phase system, an aqueous, .. hydrophilic and hydrophobic intractions, medium high medium. 7 seporation depend on physical or chemical of sephadex has both hydrophobic and hydrophilic. ③ Both a solutes and a solvent are components of a solution which is a homogenous mixture many sol? Separating immiscible liquids is done simply using seprating funnd, ③ Two liguid are put into the funne and left for a short on csut into the funnel and are left for o short time tosettles but and from two fayers
