Concept explainers
(a)
Interpretation:
The given solutions need to be classified in homogenous, heterogeneous, or colloidal mixtures.
Concept Introduction:
The solutions which are having uniformity in its composition and properties is called as Homogenous mixture. The solution mixture which contains visibly differentiated particles or phases then it is called as heterogeneous solution. The solution contains the solids which are suspended in to liquid medium is known as colloidal solution.
(b)
Interpretation:
The given solutions need to be classified in homogenous, heterogeneous, or colloidal mixtures.

- 6-18 Suppose you prepare a solution by dissolving glucose in water. Which is the solvent, and which is the solute?arrow_forward6-111 As noted in Section 6-8C, the amount of external pressure that must be applied to a more concentrated solution to stop the passage of solvent molecules across a semipermeable membrane is known as the osmotic pressure The osmotic pressure obeys a law similar in form to the ideal gas law (discussed in Section 5-4), where Substituting for pressure and solving for osmotic pressures gives the following equation: RT MRT, where M is the concentration or molarity of the solution. (a) Determine the osmotic pressure at 25°C of a 0.0020 M sucrose (C12H22O11) solution. (b) Seawater contains 3.4 g of salts for every liter of solution. Assuming the solute consists entirely of NaCl (and complete dissociation of the NaCI salt), calculate the osmotic pressure of seawater at 25°C. (c) The average osmotic pressure of blood is 7.7 atm at 25°C. What concentration of glucose (C6H12O6) will be isotonic with blood? (d) Lysozyme is an enzyme that breaks bacterial cell walls. A solution containing 0.150 g of this enzyme in 210. mL of solution has an osmotic pressure of 0.953 torr at 25°C. What is the molar mass of lysozyme? (e) The osmotic pressure of an aqueous solution of a certain protein was measured in order to determine the protein's molar mass. The solution contained 3.50 mg of protein dissolved in sufficient water to form 5.00 mL of solution. The osmotic pressure of the solution at 25°C was found to be 1.54 torr. Calculate the molar mass of the protein.arrow_forward6-113 List the following aqueous solutions in order of decreasing freezing point: 0.040 M glycerin (C3H8O3) 0.025 M NaBr, and 0.015 M AI(NO3)3 Assume complete dissociation of any salts.arrow_forward

Explain.arrow_forward6-68 If we add 175 g of ethylene glycol, C2H6O2, per 1000. g of water to a car radiator, what will be the freezing point of the solution?arrow_forward6-20 Give a familiar example of solutions of each of these types: (a) Liquid in liquid (b) Solid in liquid (c) Gas in liquid (d) Gas in gasarrow_forward
- 6-55 According to the label on a piece of cheese, one serving of 28 g provides the following daily values: 2% of Fe, 6% of Ca, and 6% of vitamin A. The recommended daily allowance (RDA) of each of these nutrients are as follows: 15 mg Fe, 1200 mg Ca, and 0.800 mg vitamin A. Calculate the concentrations of each of these nutrients in the cheese in ppm.arrow_forward6-53 Dioxin is considered to be poisonous in concentrations above 2 ppb. If a lake containing L has been contaminated by 0.1 g of dioxin, did the concentration reach a dangerous level?arrow_forward6-74 An osmotic semipermeable membrane that allows only water to pass separates two compartments, A and B. Compartment A contains 0.9% NaCI, and compartment B contains 3% glycerol C3H8O3. (a) In which compartment will the level of solution rise? (b) Which compartment (if either) has the higher osmotic pressure?arrow_forward

Based on the data in Table 8-1, should this solution be characterized as a. saturated or unsaturated b. dilute or concentratedarrow_forward6-39 Assuming that the appropriate volumetric flasks are available, describe how we would make these solutions: (a) 175 mL of a 1.14 M solution of NH4Br in water (b) 1.35 L of a 0.825 M solution of Nal in water (c) 330 mL of a 0.16 M solution of ethanol, C2H6O, in waterarrow_forward
