Give an example of a strong base by name and formula.
answers will vary, might include: sodium hydroxide, NaOH potassium hydroxide, KOH calcium hydroxide, Ca(OH)2
100
The two pieces of the Arrhenius acid definition.
What are it produces H+ in aqueous solutions?
200
The value that is used to express the acidity or basicity of a system.

This describes a solution with pH of 7.
What is neutral?
200
Red litmus turns this color in an acid.
What is it stays red?
200
When a strong base is dissolved in water, it produces a solution containing a high concentration of this.
What is hydroxide ions (OH-)?
200
(*** BONUS *** 3X point value) The conjugate base for formic acid, HCOOH.
What is HCOO-? (score +/- 3X points)
300
An ionic compound that forms when a metal atom replaces the hydrogen of an acid.
What is a salt?
300
The usual low to high range for pH values.
What is 0 - 14?
300

What is yellow? (Score +/- 600 points)
300
The taste of acidic and basic compounds, respectively.
What is an acid is sour/tart and a base is bitter/brackish?
300
The conjugate acid in the equation: NH3 + H2O --> NH4+ + OH-
What is NH4+?
400
The name of the variable ka, which is related to how much of a weak acid dissociates.
What is the acid ionization constant?
400
In NH3 and NaOH solutions of equal molarity, the one with the higher pH value and the reason.
What is NaOH because it is a strong base and completely dissociates, creating more OH- ions per mole than NH3 (a weak base)?
400
