Ch. 4 Flashcards
What are solutions
A homogeneous mixture of two or more pure substances
What is a solution called when water is the solvent?
Aqueous solution
When does dissolution occur
Occurs when ion is formed from the Solvation process
What is morality
Moles per solute per volume of solution in liters
What are the 3 electrolytes
Strong, weak, nonelectrolyte
What is a strong electrolyte
Dissociates completely when dissolved in water
What is a weak electrolyte
Only dissociates partly when dissolved in water
What is a nonelectrolye
Does not dissolvable in water
What Is chemical equilibrium
The state where the amount of product formed and lost are equal and no increase/decrease of product occurs
Ionic compounds, that are electrolytes,________________.
Dissociates in water
What are precipitation reactions
Reaction that results in the formation of an insoluble product
What is oxidation
Loss of electron
What is reduction
Gain of electron
Combustion
A chemical reaction between substances
Combination
Two or more elements or compounds combine to form a single compound
(Synthesis reaction)
Decomposition
Process/effect of simplifying a single chemical entity into two or more fragments
Neutralization
Chemical reaction in which acid and a base react quantitively with each other
Single-placement reaction
Chemical reaction in which one element is substituted for another element in a compound
What are oxidation reduction reactions?
The transfer of electrons between reactants forming the products
Molecular equation
When the complete chemical formulas of all reactants and products are used
Acids
Proton donors; they increase the concentration of H+
Bases
Proton acceptors; they increase the concentration of OH-
Exchange reactants
When cations and anions appear to exchange partners
Complete ionic equation
Shows all dissolves strong electrolytes as their component ions
