DB Acqueous Vocab

Definitions for acqueous vocabulary

QuestionAnswer
Solution Chemistry Vocabulary
Solute The substance that is dissolved in a solution. For solutions of fluids, the solvent is present in greater amount than the solute
Solvent The component of a solution that is present in the greatest amount. It is the substance in which the solute is dissolved
Solution A solution is a homogeneous mixture of two or more substances. A solution may exist in any phase
Aqueous of, or relating to water
Freezing Point depression A solution is a homogeneous mixture of two or more substances. A solution may exist in any phase
Boiling Point elevation the phenomenon that occurs when the boiling point of a liquid is increased when another compound is added, such that the solution has a higher boiling point than the pure solvent.
Saturated A substance in which the atoms are linked by single bonds. A fully saturated compound contains no double or triple bonds
Unsaturated When referring to solutions, being able to dissolve more solute. When referring to organic compounds, containing double or triple carbon-carbon bonds
Supersaturated to be more highly concentrated than is normally possible under given conditions of temperature and pressure
Distillation technique of heating a liquid to create vapor which is collected when cooled separate from the original liquid
Filtering being put through a device (usually a membrane or layer) that is designed to block certain objects or substances whilst letting others through
Chromatography a method of separating and analyzing mixtures of chemicals
Solubility maximum amount of solute that may be dissolved in a solvent
Mixture one or more products together forming a compound
Homogeneous substance or material that contains only one kind of compound or one element
Heterogeneous substance or material that contains more than one compound or element
Suspension heterogeneous mixture in which solute-like particles settle out of solvent-like phase
Colloid type of homogeneous mixture in which the dispersed particles do not settle out
Dissociation separation of ions that occurs when a solution dissolves
Electrolyte A substance which forms ions in an aqueous solution
Nonelectrolyte Ethyl alcohol (ethanol) is a nonelectrolyte because it does not ionize when dissolved in water
Precipitate solid that is produced as a result of a chemical reaction in the solution and that seperates from the solution
Ionic equation Chemical equation for a reaction which lists only those species participating in the reaction
Molecular equation An expression which states the number and type of atoms present in a molecule of a substance
Spectator ion an ion that does not take part in a reaction and is found in solution both before and after the reaction
Acid An acid is a chemical species that donates protons or hydrogen ions and/or accepts electrons
Base chemical species that donates electrons or hydroxide ions or that accepts protons.
Neutralization chemical species that donates electrons or hydroxide ions or that accepts protons
Oxidation reaction in which the atoms or ions of an element experience an increase
Reduction
Molarity a concentration unit, defined to be the number of moles of solute divided by the number of liters of solution.
Molality a unit of concentration, defined to be equal to the number of moles of solute divided by the number of kilograms of solvent.
Dilution Process of reducing the concentration of a solute in solution, usually simply by mixing with more solvent
Titration the process in which one solution is added to another solution such that it reacts under conditions in which the added volume may be accurately measured
Concentration amount of a substance per defined space. Concentration usually is expressed in terms of mass per unit volume

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.
