Question 1

Normal saline solution is 0.90% (w/v) NaCl. A solution that is 0.10 % NaCl is ___.

Accepted Answer

A solution that is 0.10% NaCl is hypotonic compared to normal saline solution (0.90% NaCl) because it has a lower concentration of solutes.

Question 2

When red blood cells are placed into a NaCl solution more dilute than 0.9% (w/v), which is the same solute concentration as found inside the cells, they will undergo ___ since dilute solution is ___.

Accepted Answer

Crenation occurs when red blood cells are placed in a hypertonic solution, causing them to shrink. Hemolysis occurs in a hypotonic solution, where water enters the cells, causing them to swell and potentially burst. Since the solution is more dilute than 0.9% NaCl, it is hypotonic relative to the inside of the cells, leading to hemolysis.

Question 3

When a cucumber is placed into a concentrated salt solution (brine) during the pickling process, the cucumber will shrivel because water will move from the ___ to the ___ and this process is known as ___.

Accepted Answer

Water moves from the cucumber (where there is a higher concentration of water) to the salt solution (where there is a lower concentration of water) through the process of osmosis, which is the movement of water across a semipermeable membrane from an area of high water concentration to an area of low water concentration.

Question 4

If red blood cells were to be stored in a hypertonic solution in the blood bank, then

Accepted Answer

Storing red blood cells in a hypertonic solution would cause water to flow out of the cells due to osmosis, leading to cell shrinkage and wrinkling.

Question 5

Barometers measure atmospheric pressure and temperature.

Accepted Answer

Barometers measure atmospheric pressure, not temperature.

Question 6

The atmospheric pressure is greater at the top of the mountain than in the valley below.

Accepted Answer

Atmospheric pressure decreases with an increase in altitude, so it is lower at the top of a mountain than in the valley below.

Question 7

For a barometer constructed by filling a glass tube with mercury and carefully inverting the tube into a mercury-filled dish, the greater the pressure pushing down on the mercury in the dish, the shorter the column of mercury.

Accepted Answer

The greater the pressure pushing down on the mercury in the dish, the higher the column of mercury will rise in the tube. This is because the increased pressure forces more mercury up into the tube to balance the pressure difference.

Question 8

The calculations of Boyle's, Charles', and Gay-Lussac's laws assume that the gases involved behave as ideal gases.

Accepted Answer

These laws are based on the ideal gas assumption, which simplifies the behavior of gases by ignoring intermolecular forces and the volume occupied by the gas molecules themselves.

Question 9

The solute of a solution is usually present in greatest amount.

Accepted Answer

The solute is the substance that is dissolved in the solvent, and the solvent is usually present in a greater amount than the solute in a solution.

Question 10

Henry's law predicts that the higher the pressure the smaller the solubility of a gas in a liquid.

Accepted Answer

Henry's law states that at a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid. This means that the higher the pressure, the greater the solubility of the gas in the liquid.

Question 11

The particles of a colloid are larger than the particles of a solution.

Accepted Answer

Colloidal particles are larger than the particles in a solution but smaller than those in a suspension, making them intermediate in size.

Question 12

Red blood cells will shrink in a hypotonic solution.

Accepted Answer

Red blood cells will swell and possibly burst in a hypotonic solution because water moves into the cells where the concentration of solutes is higher.
