Solutions, Acids, and Bases Flashcard

Solution
Homogeneous mixture of two or more substance in one phase. One substance dissolved in another.
Solute
Substance that is dissolved
Solvent
Substance that does the dissolving; most abundant
Aqueous Solution
Any solution that uses water as a solvent.
Universal Solvent
Water
Molarity
Number of mols of solute dissolved in ever liter of solution
Molality
Mols of solute dissolved in kilograms of solvent
Saturated Solution
When a solution reaches the point where it cannot dissolve any more solute. At this point it has reached maximum concentration.
What affects solubility?

– Temperature

– Pressure

– Solute-Solvent Attraction

Supersaturated Solution
Solutions that contain more solute then solvent would normally dissolve under current conditions.
Acid
A substance that can donate a Hydrogen Ion in a solution
Base
A substance that can gain a hydrogen ion
Acid
Sour, Corrosive, Reacts with Metals, Reacts with carbonates
Base
Bitter taste, corrosive, reacts with acids, conduct electricity
Conjugate Base
When an acid loses a hydrogen ion
Conjugate Acid
When a base gains a hydrogen ion
Indicators
Distinguish the difference between acid and bases using colors to distinguish the difference depending on pH
pH
strength or acid or base
pH
power of hydrogen, a measure of the concentration of hydrogen ions in a solution
Strong Acid
100% disassociates in water; produces many hydrogen ions
Weak Acid
.04% dissociates in water; produces very few hydrogen ions
Strong Bases
Have a strong hydrogen ion attraction in a solution
Weak Bases
Have a low hydrogen ion attraction in a solution
Neutralization Reaction
When an acid and base react in the proper amounts
Standard Solution
A solution with a known concentration
Equivalence point
When the moles of acid and moles of base are equivalent
