chem exam 4

QuestionAnswer
coordinate covalent bond the bond that occurs when 1 atom transfers an electron pair to another seen formed between Lewis acids/bases
dative bond other term for coordinate covalent bond
lewis acid-base adduct the compound that forms when you make a coordinate covalent bond/ when a lewis acid/base react compound that contains a coordinate bond between the lewis acid & base
complex ion formed when a metal cation and lewis base react to transfer electrons and therefore form a coordinate covalent bond "ion formed from a metal ion with a lewis base via a coordinate covalent bond" to be proper...
ligand the lewis base that bonds with a metal ion to form a complex ion
stability constant aka formation constant Kf
dissociation constant Kd
solubility product constant Ksp at a compounds Ksp value, the solution is exactly saturated any lower of a value and a precipitate forms "the max amount of solute that can be dissolved in water before solid forms"
molar solubility s molarity of a SATURATED solution
ion product Qc solubility product expression evaluated
how to convert s between g/L to mol/L and vice versa; what molar mass do you use? use the molar mass of the compound solid that is dissociating/ the precipitate
smaller Ksp LESS soluble won't dissociate very much we like when Ksp is small cause we can neglect x 😛😛😛
how do common ions affect solubility when a common ion is added, solubility decreases because it pushes reaction left towards the solid reactant; more precipitate formed aka less soluble
lewis acid ACCEPTS electron pairs
lewis base DONATES electron pairs
larger Ksp much more soluble
low ksp means its mostly reactants at equilibrium aka,,,,not very soluble
when CAN you make the assumption to neglect x if its just being added to another number and Ksp is hella small ex: 0.010 + x
when CANT you make the assumption to neglect x if its involved in multiplication or division, or if its alone (and Ksp is hella small) ex: x, 2x, 4x, etc
what makes good Lewis acids cations and electron deficient species
what make good Lewis bases anions

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.
