Whether you use the term molarity, concentration or solubility they all represent the maximum amount of solute that can successfully be dissolved in a solvent.
Concept: The Rules for the Solubility of a compound5m
Certain positive ions combine with negative ions to form either a liquid, aqueous, solid or gaseous compound. The Solubility Rules help us determine which form is created.
Concept: The meaning of the terms soluble and aqueous2m
Saying a compound is soluble means that the compound will dissolve into aqueous ions in a solvent. These ions can conduct electricity and are called electrolytes.
Concept: The meaning of the terms insoluble and precipitate2m
Saying a compound is insoluble means that the compound will not dissolve into aqueous ions and forms a solid called a precipitate, which will not conduct electricity.
Concept: The Classification of Electrolytes1m
Whenever you add a solute to a solvent there are three possible outcomes: the solute dissolves completely, dissolves partially or doesn't dissolve at all into ions.
Concept: The Strong Electrolytes6m
Strong Electrolytes break up into ions completely and are broken down into 3 categories: Strong Acids, Strong Bases and Soluble Ionic Compounds.
Concept: The Weak Electrolytes2m
Weak Electrolytes partially break up into ions and are broken down into 2 categories: Weak Acids and Weak Bases.
Concept: The Non-Electrolytes2m
Non-Electrolytes do NOT break up into ions at all and are referred to as molecular compounds.
Now that we have a more firm grasp on the types of electrolytes, we can now apply this knowledge to electrolyte based questions.
Example: Each of the following reactions depicts a solute dissolving in water. Classify each solute as a strong electrolyte, a weak electrolyte or a non-electrolyte.5m
Based on the different classifications of electrolytes we can expand to other compounds.
Problem: Classify each of the following solutes as either a strong electrolyte, a weak electrolyte or a non-electrolyte.6m
A balanced molecular equation is an equation showing the neutral forms of compounds.
All that happens is that soluble ionic compounds separate and become ions in the chemical equationl. This represents the total or full ionic equation.
Concept: Writing Molecular Reactions6m
Concept: Balanced Molecular Equation5m
In a balanced molecular equation reactant compounds exist as ions that recombine to form products.
Concept: Total Ionic Equation2m
In a total ionic equation only the compounds that are aqueous can break up into ions.
Concept: Net Ionic Equation2m
In a net ionic equation the spectator ions are removed and what remains is the net ionic equation.
Remember when asked to write a complete and balanced molecular equation that a reaction only occurs if a solid, liquid or gas is formed as a product.
Problem: Predict whether a reaction occurs, and write the balanced total and net ionic equations.4m
If your chemical equation produces only aqueous products then the answer is NO REACTION.
