- 1. Water is usually softened by using an ion exchange resin to replace each Ca2+ (and Mg2+) ion with 2Na+ ions. What must be true of the Na+ salt of soap?arrow_forwardWhich statements accurately describe soap? Select one or more: Soaps are a mixture of fatty acid salts and glycerol. Soaps react with ions in hard water to create a precipitate. Soaps should be weakly alkaline in solution. aps work in solutions of any pH. Soaps are both hydrophobic and hydrophilic.arrow_forwardTrue or False: Carboxylic acids containing six or more carbon atoms per molecule are more soluble in 3 M sodiumaqueous hydroxide than in dichloromethane.arrow_forward
- On a soap molecule, identify which end is known as being polar and which end is known as being nonpolar. Based off of this analysis, label which end is hydrophobic and which one is hydrophilic. Define hydrophobic and hydrophilicarrow_forwardExplain the difference in the solubility of benzoic acid and sodium benzoate in water.Which of the two would you predict to be more soluble in CHCl3? Explain.arrow_forwardDraw the attraction between a water molecule and a molecule of PCl3 First, draw one molecule and add the partial charges where needed - use the ΔEN to determine the types of bonds. Then, draw the second molecule so that the δ+ on one molecule lines up across from the δ- on the other. Since we can't draw the molecules here you will answer questions about the drawings that you made on the homework worksheet. PCl3 has ________ bonds with a ΔEN = ________ . PCl3 has 4 REDs and is symmetrical/asymmetrical (answer is ___________ ) making it a polar/nonpolar (answer is ___________ ) molecule. Each Cl has a __________ charge and the P has a __________ charge. H2O has 2 ________ bonds with a ΔEN = +__________ . H2O has 4 REDs and is symmetrical/asymmetrical (answer is _________ ) making it a polar/nonpolar (answer is __________ ) molecule. Each H has a ___________ charge and the O has a _________ charge. The strongest possible attractive force between these two molecules…arrow_forward
- Box the functional group/s that contribute to the solubility (hydrophilic and lipophilic) of the given organic molecules then check whether the drug molecule is hydrophilic or lipophilic.arrow_forward3. What were the structural features of the molecules that were soluble in aqueous bases (5% NaOH and 5% NaHCO3) and why do these features allow these molecules to dissolve in that solvent? 4. What were the structural features of the molecules that were soluble in aqueous acid (5% HCl) and why do these features allow these molecules to dissolve in that solvent? Solubility of Known Compounds Lab Known compounds: Glycerol, Sec-butanol, Naphthalene, Triphenyl methanol, Aniline, Benzoic Acid, Dioctyl Sebacate..arrow_forwardWhich one of the compounds below has the highest solubility in water, expressed in moles per liter? a. ZnCO3, Ksp = 1.4 × 10–11 b. Cd(OH)2, Ksp = 2.4 × 10–14 c. AgI, Ksp = 8.3 × 10–17 d. CdCO3, Ksp = 5.2 × 10–12arrow_forward
- /Explain how the two vitamins below reacts with water.Ensure you use the following polar,non-polar sigma and pi bonds. Identify all the functional groups present and describe how and why they interact with water. Vitamin C (Ascorbic acid) Vitamin E (alpha-topherol) HỌ HO. HO. OH HO H₂C H₂ CH₂ CH₂arrow_forward4.Based on the boiling point and surface tension values obtained, which of the two liquids has stronger IMFA?arrow_forwardWhere does ammonia separate from water?arrow_forward
