What makes acetanilide partially soluble in cold water specifically.
Is Naphthalene soluble, partially soluble or insoluble in: (1) cold ethanol; (2) hot ethanol; (3) cold chloroform; (4) hot chloroform Is maleic anhydride soluble, partially soluble or insoluble in:(1) cold ethanol; (2) hot ethanol; (3) cold chloroform; (4) hot chloroform
3. (pts) We know that most solids are more soluble in warm water than in cold water. Does the solubility of NHCl fit this pattern? Explain.
What is the literature (known) melting point for acetanilide? A student performed a recrystallization to purify a crude sample from a reaction. The amount of crude material collected from the reaction was 13.56 grams. After the purification, the student collected 8.97 grams of extremely pure material. a. What is the percent recovery of the desired material? b. Is it possible to determine how much of the desired material remained in solution after the filtration? The solubility of acetanilide in hot...
What is the chemistry involved in purifying acetanilide by recrystallization (in water) ? Like what exactly is happening between the intermolecular forces and for the impurities to be left behind?
How would you separate a mixture of benzanilide (soluble in hot ethanol, insoluble in cold ethanol and water) and benzoic acid (soluble in hot or cold ethanol and hot water only) using recrystallization? Write out a formal procedure for this separation. It should be passive, past tense and in complete sentences. There should be detail for someone to follow, but it does not need to be a step by step procedure. You should assume it is for someone who is...
4. Solid calcium iodate, Ca(IO3)2, (MW = 389.9 g/mol) is only slightly soluble in cold water. Measurements indicate that only 0.12 g of the compound dissolve for every 100 ml of solution at 5C. Write the dissolution equation, the K expression, then determine the value of the equilibrium constant for calcium iodate dissolving in water at 5C.
You recrystallized acetanilide from water and found out that the final mixture contains 85 % of acetanilide by weight while the rest is water. Calculate MOLAR percentage of ACETANILIDE in the mixture if molecular weight of acetanilide is 135 g/mol and molecular weight of water is 18 g/mol. Round your answer to the nearest tenth, eg. 1.1 %
3. Is vitamin C a water- or fat-soluble vitamin? What is the difference between water- and fat-soluble vitamins? Which must you be more careful consuming and why?

3.Cold water is added to each of the following pairs of solid salts. In each case state whether a precipitate wil be present, and if so what its composition is. Note: The precipitate may be either one or both of the original salts or one or more of the products formed by reaction between the salts. (10 pts) a. Pb(C2H2O2)2 and NaCl b. BaSO4 and Cus c. Ni(NO3)2 and CaCl2 d. AgCl and Cu(NO3)2 e. Na2CO3 and MgCl2 4. In...
