Test 3


Colloid Mixture having particles that are moderately large. Pass through fliters but semipermeable
Concentration Measure of amount of solute that is dissolved in a specified amount of solution
Crenation The shriveling of a cell because water leaves the cell when the cell is placed in a hypertonic solution.
Dialysis A process in which water is and small solute particles pass through the semipermeable membrane
Dilution A process by which water is added (solvent) is added to a solution to increase the volume and decrease (dilute) the concentration of the solute.
Electrolyte A substances that produces ions when dissolved in water, its solution conducts electricity.
Equivalent (Eq) The amount of a positive or negative ion that supplies 1 mole of electricity.
Hemodialysis A mechanical cleansing of the blood by an artificial kidney using the principle of dialysis
Hemolysis Swelling and bursting of red blood cells in a hypotonic solution because of an increase in fluid volume
Henry's Law Solubility of a gas in a liquid is directly related to the pressure of that gas above the liquid
Hydration The process of surrounding dissolved ions by water molecules.
Hypertonic Solution A solution that has a higher particle concentration and higher osmotic pressure than cells of the body.
Solution A homogeneous mixture in which the solute is made of small particles that can pass through filters and semipermeable membranes.
solute is present in the smaller quantity.
Solubility max about of solute that can dissolve in exactly 100g of solvent .
Soluble salt An ionic compound that dissolves in water
Saturated Solution A solution containing the max amount of solute that can dissolve at a given temp.
Osmotic Pressure Pressure that prevent the flow of water into the more concentrated solution
Osmosis The flow of a solvent usually water through a semipermeable membrane into a solution of higher solute concentration
Nonelectrolyte Substance that dissolves in water as molecules. Doesn't conduct electrical current
Molarity (M) Number of moles of solute in exactly 1 L of solution
Mass/Volume Grams of solute in exactly 100mL of solution
Mass/Mass Mass percent Grams of solute in 100g of solution
Isotonic Solution A solution that has the same particles concentration and osmotic pressure as that of the cells of the body.
Insoluble salt An ionic compound that does not dissolve in water.
Hypotonic Solution A solution that has a lower particle concentration and lower osmotic pressure than the cells of the body
Solvent Substance which the solute dissolves usually component present in greatest amount
Strong Electrolyte A polar or ionic compound that ionizes completely when it dissolves in water. It solution is a good conductor of electricity
Suspension A mixture in which the solute particles are large enough and heavy enough to settle out and be retained by both fliters and semipermeable membranes.
Unsaturated Solution A solution that contains less solute than can be dissolved
Volume Percent (v/v) Percent concentration that relates the volume of the solute in exactly 100 ml of solution
Weak electrolyte A substance that produces only a few ions along with many molecules when it dissolves in water. Weak conductor of electricity
Acid Substance that dissolves in water and produces hydrogen ions .
Acidosis Physiological condition in which blood pH is lower then 7.35
Alkalosis Blood pH is higher than 7.45
Base Dissolves in water and produces hydroxide ions according to the Arrhenius Theory
Bronsted-Lowry acids and bases An acid is a proton donor and a base is a proton acceptor
Buffer A solution of a weak acid and its conjugate base or weak base and its conjugate acid that maintains the pH by neutralizing added acid or base
Conjugate acid base pair An acid and its conjugate that differ by one H, Acid donates proton the product its conjugate base which is capable of accepting proton. conjugate base
Hydronium Ion Ion formed by the attraction of a proton H to a H20 molecule
