Acid-Base Definitions
What is an Bronsted-Lowry Acid?
Donates H+.
What Does pH Measure?
Hydrogen Ion Concentration.
What is a Neutralization Reaction?
Reaction Between an Acid and a Base to Form a Salt and Water.
What is an Indicator in the Context of Acid-Base Chemistry?
Substance That Undergoes a Color Change to Indicate pH.
The purpose of a titration.
What is determining the concentration of a solution where concentration is not known?
What is a Bronsted-Lowry Base?
Accepts H+.
Calculate The pH of a Solution With a Hydrogen Ion Concentration of 1 x 10^-4 M.
pH=4.
In an Acid-Base Titration, What Indicates The Endpoint of the Reaction?
Indicator or pH Meter.
Which Indicator is Commonly Used to Determine the Endpoint in an Acid-Base Titration of a Strong Acid with a Strong Base?
Phenolphthalein.
A buffer prevents large changes to this when a relatively small amount of a strong acid or base is added to a solution.
What is a pH change?
What Characterizes a Strong Acid?
Complete Ionization.
Kb, Ka and Kw relate in this way.
What is Kw = Ka * Kb?
Define a Conjugate Acid in The Context of Acid-Base Reactions.
Formed When a Base Accepts a Proton (H+).
What Color Does Phenolphthalein Turn in an Acidic Solution?
Colorless.
Buffers work because of this principle.
What is le Chatelier's Principle
Acts as both an acid and a base in all theories.
What is an Amphoteric Substance?
Define pOH.
Negative Logarithm of Hydrogen Ion Concentration.
What is the Difference Between a Strong Acid and a Weak Acid in Terms of Their Reaction With Water?
Strong Acid Fully Ionizes in Water, While Weak Acids Partially Ionize.
An indicator is a B-L acid base pair with this special property.
What is a different colour of the acid and conjugate base?
A buffer is made of up of this.
A weak acid and its conjugate base or a weak base and its conjugate acid
Has more than one proton to donate.
What is polyprotic
Calculate The pH of a Solution With a Hydrogen Ion Concentration of 1 x 10^-8 M.
pOH=8.
In a Reaction Between an Acid and a Base, if the Acid is Strong, What Can You Say About the Strength of its Conjugate Base?
Conjugate Base of a Strong Acid is Weak.
What Indicator Would be Appropriate for Titrating a Weak Acid With a Strong Base?
Methyl Orange.
The pKa of the indicator should roughly equal this at a titration's end point
What is the pH of the titration's end point?
