Part 3. Solubility. For the following molecules label whether you think it will be more soluble in water (H₂O) or dichloromethane (CH₂Cl₂) at 25 °C. OH НО OH ОН ОН OH

Which of the following phrases best describes the term solubility?             the ability of a solvent to dissolve in a solute       the ability of a solute to dissolve in a solvent       the maximum amount of solute that will dissolve in solvent at a given temperature       the maximum amount of solvent that will dissolve in a solute at a given temperature       the amount of solvent that dissolves in a solute for each 10oC rise in temperature

46.29 g of KOH is dissolved in 250. mL of water. (Please pay attention to sig figs!) What is the mass percent of KOH in this solution? (use the density of water 1.00g/mL) a. b. What is the concentration, expressed in molal (m = moles solute/kg solvent), of this initial solution? What is the concentration, expressed in molar (M = moles solute/liters solvent), of this initial solution? (assume that the addition of the KOH to the water did not change the C. volume, which is still 250.mL) d. If I add 500.mL of pure water to this 250.mL solution, what is the new concentration expressed in molar (M)? (Careful, what is the new volume after mixing?) e. If, instead, I took the 250. mL solution and evaporated the water until the solution had a volume of 150.mL, what would be the concentration of this this new solution expressed in molar (M)?

The solubility of a compound is 84 g per 100.0 g solvent at 25 °C. If 84 g of the compound is dissolved in 200.0 g of solvent at 25 °C, the solution is dilute unsaturated saturated supersaturated

! T 1 A Z The names and chemical formulae of some chemical compounds are written in the first two columns of the table below. Each compound is soluble in water. Imagine that a few tenths of a mole of each compound is dissolved in a liter of water. Then, write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution. For example, you know water itself will be present, so you can begin each list with the chemical formula for water (H₂O). -6 Note: "major" chemical species are those present in concentrations greater than 10 mol/L. 89 FI compound propylene glycol Explanation ammonium lodide @ 2 glycerol W S X command Check 30: F2 # 3 formula C,H, (OH)₂ C₂H₂O, NH₂L 20 E E D 8.0 F3 C $ 4 R major species present when dissolved in water F a F4 % 5 V 0 0 T I F5 G 6 B F6 Y 7° H X & 7 00 stv N K F7 U 0.0.... 3 J © 2023 McGraw Hill LLC.
