Acid and Base concepts

100

This is the definition of pH. 

What is -log [H+]?

200

This is the reason weak acids are called "weak." 

What is partial ionization? 

300

These solutions resist changes in pH upon addition of small amounts of acid or base. 

What are buffer solutions? 

400

This equation relates pH, pKa, and the ratio of the concentrations of an acid and it's conjugate base. 

What is the Henderson-Hasselbach equation? 

500

This is the term for a substance that can act as both an acid and a base. 

What is amphoteric? 

Equilibrium

100

This side of the reaction is favored when Q is greater K.

What are reactants?

200

When heat is added, this side of the reaction is favored in an Endothermic process.

What are products? 

300

This is the point in a titration where the amount of acid is stoichiometrically equal to the amount of base. 

What is the equivalence point? 

400

This is the principle that if a change in condition is applied to a system in equilibrium, the system will shift in a direction that relieves the stress. 

What is Le Chatelier's Principle? 

500

This is the pH of a weak acid C₆H₅OH in a 0.75M solution. K_a = 1.12 *10^-10.

What is 5.04?

Strong Acids/Bases

100

This is the reason a strong acid is called strong.

What is full ionization? 

200

This is the conjugate acid of Ammonia, NH₃.

What is NH₄?

300

This is the pH of a 0.0015 M KOH solution.

What is 11.18?

400

This type of acid has more than on ionizable proton per molecule. 

What is polyprotic?

500

This is how you find K_a if you know K_b. 

What is the ion product constant for water (K_w)?

Acid Base Trivia

100

An acid usually tastes (blank), while a base usually tastes (blank). 

What is sour, and bitter? 

200

This common household item often has a pH of 2.4.

What is vinegar?

300

Acids and bases contain these, which allow them to conduct electricity when dissolved in water. 

What are electrolytes? 

400

This type of paper turns red in the presence of acids and blue in the presence of bases. 

What is Litmus paper? 

500

Some ants use this type of acid as a self-defense mechanism. 

What is formic acid? 

Trivia

100

This element is of the most abundance on earth.

What is Oxygen?

200

This common substance is technically a liquid high an extremely high viscosity. 

What is glass? 

300

This Polish scientist was credited with discovering two elements, and coined the term 'Radioactivity'. 

Who is Marie Curie?

400

The world's largest and highest-energy particle accelerator, or the Large Hadron Collider is located here.

Where is Geneva, Switzerland?

500

This is a vital industrial process for producing ammonia (NH₃), and is often called one of the most significant technological advances of the 20th century. 

What is the Haber-Bosch process?
