Concept explainers

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

Question

Practice Problem #1: Rubbing alcohol is sold over the counter as a topic (skin) antiseptic. Rubbing alcohol is typically 70% (v/v) iso-propyl alcohol,
C3H,OH, in water. How much of this solution can you prepare with 500 mL of pure C3H-OH?
Teacher's Note: Again, most concentration problems will have two (2) quantities. Percent by volume (% v/v) is not a good starting point because it is a
ratio (a conversion factor). So, look at the other quantity as your dimensional analysis start point. Write the volume quantity, units, and "of what", over
the number 1.]

2. Henry's law in the emergency room! The partial pressure of oxygen in the lung alveoli is a bit less than in air, being about 100 mm of mercury, or.13 Atm. In saline/glucose solution (lacking any hemoglobin) at 37° C, oxygen will equilibrate with alveolar air to a concentration of about 3 mg/L (or 0.093 mM). In oxygen-saturated blood, however, the O, concentration is about 0.008 M (8 mM). A. What is the Henry's Law constant for these two situations (with or without hemoglobin)? B. By what factor does the presence of hemoglobin enhance oxygen solubility in blood? C. Given the above, imagine you are an emergency room doctor treating a patient who lost half of their red blood cells in an accident, and received cell-free plasma from a paramedic to keep their blood pressure up. Nevertheless, the patient is short of breath and not doing well. If you had a choice between administering extra oxygen or giving a blood infusion to restore the red blood cell count, which would be more helpful?…
