Chemistry Key Terms

TermDefinition
complex ion a charged species consisting of a metal ion surrounded by ligands
formation (stability) constants the equilibrium constant for each step of the formation of a complex ion by the addition of an individual ligand to a metal ion or complex ion in aqueous solution
ion product the product of the initial concentrations of the ions of a given solid in a solution; represented by Q and compared to the solubility-product constant (Ksp) to determine if precipitation will occur
qualitative analysis separating a mixture containing all the common cations into five major groups based on solubilities; each group is then treated further to separate and identify the individual ions
selective precipitation a method of separating metal ions from an aqueous mixture by using a reagent whose anion forms a precipitate with only one or a few of the ions in the mixture
solubility product constant (solubility product) the constant for the equilibrium expression representing the dissolving of an ionic solid in water

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.
