Partition (or Distribution) Coefficient I best way to think about this is to start with a solute that is not in solution, then add a mixture (Not a homogeneous mixture! Why?) of water (or aqueous acid or base) and an organic solvent (such as diethyl ether). Swirl the solute with the solvent mixture until everything is dissolved. Then let it stand, because two immiscible solvents where used, you will have two layers. (Question: Which solvent will be on top, which on the bottom?

In bromine water test Procedure: -Add 3 ml of phenol and ethanol in separate test tube-Add 10 ml of water to each test tubes-Transfer to bigger test tubes-For phenol and ethanol, Add bromine water drop by drop until bromine color persists MUST DO: Observe formation of precipitate P.s I provided photos for better visualization of the overall result procedure, I just need a further and detailed answer based on observation. If answered properly I will upvote, I promise tyyy. Please do focus on the formation of precipitate, thank youuu The first photo is the phenol one (colored one) and the second one is the ethanol (clear one)

The substance to be analyzed – is white, highly soluble in water salt. Flame coloration test gives carmine red color. Interaction with concentrated sulfuric acid leads to evolving of gas with pungent odour. Interaction with weak sulfuric acid solution leads to white precipitate formation. Interaction with water solution of silver nitrate leads to formation of white curdy precipitate, which soluble in A saturated ammonium carbonate solution. What kind of substance is this? | SrCl2 NaNO2 MgCl2 Ca(NO3) 2
II. A Study of Intermolecular Forces of Attraction Anna Divi, a young and ambitious researcher, is planning to put up her very own research laboratory. However, she does not have the funds for this to happen. She then approached Alan Read, CEO of a well-known funding agency, to help her pursue her dream laboratory. Before Alan considers Anna's proposal, Anna must perform an experiment on determining the melting point of solutions. She must have an accurate result with a percent error not greater than 3%. The data on the experiment is given below. Help Anna achieve her goals by performing the necessary calculations below. Table 1. Data on the determination of the melting point of the solution. Parameters Values Theoretical freezing point of solvent, °C 65.8 Freezing point depression constant (ke) 2.49 of solvent, 'C m1 0.250 mass of solute, g mass of solvent, g 2.100 molar mass of solute, g 148.21 mol

. Consider the two molecules shown here. 1-butanol (1)- 7.3g/100ml and butyric acid (2)- miscible The solubilities of each in water is given. What is “solubility”? What does the solubility value given for (1) here mean? Please explain, based on their structures, why the solubility of (2) is greater than the solubility of (1) in water. For a complete answer, you should start with the types of IMFs involved in the different parts of the dissolving process. You should also use the kind of reasoning from class regarding the contributions…
