IPC Unit 4 Solutions

TermDefinition
Adhesion tendency of water be attracted to other substances
Cohesion tendency of water to be attracted to another water molecule
Polar Molecule water has an uneven sharing of electrons; hydrogen has a slight positively charged and oxygen has a slight negatively charged
Aqueous solution with water as the solvent
Solute part of the solution which is dissolved
Solvent part of the solution which does the dissolving
Solution mixture made up of a solute and a solvent
Universal Solvent water easily dissolves polar and ionic substances ; ex: salt
pH scale measure of the concentration of hydrogen ions (H+) in a water based solution
Solubility of Gas will increase with low temperature and high pressure
Role of Cell Membrane maintain homeostasis with the movement of water through a selectively permeable membrane
Homeostasis internal and external balance within an organism
Osmosis the movement of water toward an area with high solute concentration ; the movement of water from an area of high water concentration to an area of low water concentration
High Heat Capactiy aids in sudden change of temperature; it requires a large amount of thermal energy to raise the temperature of water
Surface Tension caused by cohesion ; water molecules on the surface hold more tightly than molecules under
Capillary Action caused by cohesion and adhesion; water molecules climb up the xylem of plants
Covalent Bonds the hydrogen atoms and oxygen atom of a water molecule are held together by ____________________.
Hypotonic Solution the solution has less solutes and more water ; will cause water to move into the cell and swell
Hypertonic Solution the solution has more solutes and less water ; will cause water to move out of the cell and shrink
Isotonic Solution the solution has equal amounts of solutes and water inside and outside of the cell ; water will move equally into and out of the cell

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
