### Adsorption and Chromatography - Practice Questions#### Question 5Arrange the following compounds in order of their increasing adsorption tendencies.- **Option A:** Cellulose >> starch >> calcium carbonate >> alumina- **Option B:** Cellulose >> starch >> alumina >> charcoal- **Option C:** Charcoal >> cellulose >> alumina >> starch- **Option D:** Calcium carbonate >> alumina >> starch >> cellulose#### Question 6What is a common stationary phase in column chromatography?- **Option A:** iron(III)chloride- **Option B:** magnesium oxide- **Option C:** alumina- **Option D:** sodium sulfateIn these questions, the goal is to demonstrate an understanding of adsorption principles and chromatography techniques. Adsorption refers to the process by which molecules adhere to the surface of solids or liquids. Chromatography is a technique used to separate components in a mixture based on their interactions with a stationary and a mobile phase. Common stationary phases in chromatography include alumina and silica gel, known for their efficacy in separating compounds based on polarity and adsorption capabilities. **Question 27****What is the Analyte?**- ( ) Substance that needs to be separated- ( ) Substance found as impurity- ( ) A and B- ( ) None of the above**Question 28****Chromatography involves two mutually ___________**- ( ) None of the mentioned- ( ) Soluble phases- ( ) Miscible phases- ( ) Immiscible phases

Column Chromatography is a technique which is used to purify compounds depending on their polarity.…

m/ilmn/takeAssignment/takeCovalentActivity.do?locator-assignment-take [Review Topics] Submit Answer When a patient has blood cleansed by hemodialysis, the blood is circulated through dialysis tubing submerged in a bath that contains the following solutes in water: 0.6% NaCl, 0.04% KC1, 0.2% NaHCO3, and 0.72% glucose (all percentages are w/v). Suggest one or more reasons why the dialysis tubing is not submerged in pure water. progress [References] (Select all that apply.) Osmall solute ions and molecules will not pass through the dialyzing membrane O more water would flow into the blood, while more of the solutes would flow out of the dialysis tubing than desired O the blood needs to be cleaned without stripping it of too many of the needed ions and small molecules in the blood A Retry Entire Group 1 more group attempt remaining Previous Email Instructor Next Save and Exit
