chapter 16

QuestionAnswer
common ion effect the shift in equilibrium caused by the addition of a compound having an ion in common with the dissolved substance
What suppresses the ionization of a weak acid or weak base the presence of a common ion
Henderson-hasselbalch equation ph= pKa+ log [cojugate base]/[acid]
What is a buffer solution? 1. A weak acid or weak base and 2. the salt of the weak acid or weak base BOTH MUST BE PRESENT!
What does a buffer solution do? it has the ability to resist changes in ph upon the addition of small amounts or either acid or base.
What is a titration? It is when a solution of accurately known concentration is gradually added to another solution of unknown concentration until the chemical reaction between the two solutions is complete.
Equivalence point the point at which the reaction is complete
Indicator substance that changes color at (or near) the equivalence point
Ksp product solubility constant
molar solubility (mol/L) is the number of moles of solute dissolved in 1 L of a saturated solution
Solubility (g/L) is the number of moles of solute dissolved in 1L of a saturated solution
What decreases the solubility of a salt? the presence of a common ion
complex ion is an ion containing a central metal cation bonded to one or more molecules or ions
formation constant or stability constant (Kf) is the equilibrium constant for the complex ion formation

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.
