Chemistry QTR 2

Chemistry Quiz 3

QuestionAnswer
True Solution Homogenous mixture of two or more substances
Tinsure Solvent is alcohol
Aqueous SOlution Solvent is water
Alloy Solid mixture
Solute The substance that is dissolved
Solvent Substance doing the dissolving
Vechile Another word for solvent
Solubility How well something dissolves
Polar Molecule Two or more different atoms creating electronegativity
Non-Polar Molecule Two or more of the same atom
Concentration Amount of solvent
diluted solution Very low amount solute
Concentrated solution High level of solute
Saturated solution Holds all of the solute possible at that temperature and pressure
Unsaturated Not reached saturation
Supersaturated The solution contains more solute than usual. Is very unstable.
% by mass Mass of solute/ total weight of solution x 100
% by volume Volume of solute/ total volume of solution x 100
Ratio weight of solute to solution
Parts per million mg of solute/L of solution
Parts per billion (ppb) ug of solute/L of solution
Parts per trillion (ppt) ng of solution/ L of solution
Index concentration of formaldehyde in embalming fluid
Factors influcing solubility Nature of solvent, temperature, pressure
How does nature of solvent affect solubility? Like dissolves like. Polar dissolves polar, non polar dissolves non polar
How does temperature affect solubility? Solubility of gas decreases as temperature increases. Hot water embalming is less effective
How does pressure affect solubility? Solubility of gas increases as as partial pressure above solution is increased
Relationship between embalming and osmosis? Normal moisture- slightly hypotonic Edema- hypertonic Dehydrated- hypotonic
True solution characteristics Particle size < 1 nm Invisible Particles pass through membranes and filters Molecular movement Particles do not settle
Colloids Particle size 1-100 nm Visible with electron microscope Particles pass through filter but not membrane Brownian (random) movement Particles do not settle
Suspension Visible by naked eye Move by gravity Particle size >100 nm Particles do not filter Settle

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.
