Solutions & Equilibrium Flashcards
(16 cards)
Solute definition
The substance that dissolves in the solvent
Solvent defintion
The substance that the solute dissolves in
Saturated definition
A solution that contains as much solute as can be dissolved in that solution at that temp
Unsaturated definition
A solution in which more solute can be dissolved than is dissolved already at that temp
Supersatured definition
A solution that contains more solute than a saturated solution will hold at that temp
Concentrated definition
A solution in which a relatively large amount of solute is dissolved in a solution
Endothermic defintion
When heat is added to the reactants
Exothermic definition
When heat is added to the products
Dilute definition
A solution in which a relatively small amount of solute is dissolved in a solution
If an equation shifts right, the Reactants ______ and the Products ______
Decrease, increase
If an equation shifts left, the Reactants ____ and the Products ____
Increase, decrease
Different ways to stress a system at equilibrium?
Increase/decrease temp, remove/add substances, increase/decrease pressure
What is solubility
The amount a substance that dissolves in a given volume of solvent or solution at a given temp
What does it mean for a reaction to be at equilibrium
It means that the rate of the forward reaction is equal to the rate of the reverse reaction
Molarity
Moles of solute/liters of solution
Catalyst
Increases the reaction rate
