What is Equilibrium?

General state in which opposing forces or influences are balanced

100

What is a catalyst?

A substance that increases the rate of a chemical reaction

100

What should be the only substance that is neither an acid nor a base?

Water

100

What color do bases turn when phenolphthalein indicator is put into them?

Pink

100

What do you get when you combine a H+ ion with an OH- ion?

H2O, water

200

What is Dynamic Equilibrium?

A closed system where opposing processes are at equal rates. 

200

What is Physical Equilibrium?

When two opposing physical processes are balanced. 

200

How did early man describe Acids and Bases?

Acids taste sour, bases taste bitter. 

200

What should be the pH of a perfectly neutralized solution?

7 exactly 

200

What is Le Chatliers Principle?

If a stress (such as changings concentrations, changing pressure, changing temperature) is placed on a system in dynamic equilibrium, a new equilibrium will be established in such a way as to relieve the stress. 

300

What are Indicators?

Special chemicals used to identify acids or bases

300

What does Amphiprotic mean?

Compounds that can act both as an acid or a base

300

How did Bronsted/Lawry describe acids and bases?

Acids are proton donors, and bases are proton receivers. 

300

What is the general equation for a neutralization reaction?

Acid + Base => Water & a Salt

300

How did Savante Arhenius describe acids and bases?

Acids have H+ and Bases have OH-

400

What is Molarity?

A reference to how strong an acid or base is.

400

What is a Titration?

Quantitatively adding an acid to a base or a base to an acid to reach equilibrium 

400

What are three properties of bases?

Tastes bitter, slippery to the touch, tend to react and break up nonmetals, strong electrolytes, form OH- ions in water, and have a pH greater than 7

400

What will be the products of this neutralization reaction?

HBr + KOH ->

HBr + KOH -> KBr + H2O

400

What is a major problem with Savante Arhenius's definition of acids and bases?

A lot of bases don't have OH- such as ammonia NH3

500

What is the Mole Theory?

Central idea of chemistry that allows us to relate a certain number to a measurable value. 

500

What is Molar Mass?

The numerical mass of the formula of a substance in grams

500

What are four properties of acids?

Taste sour, watery to the touch, reactis with active metals, strong electrolytes, form H+ ions in water, reacts with carbonates/bicarbonates, and have a pH lower than 7

500

What will be the products of this neutralization reaction?

H3PO4 + Ca(OH)2 ->

H3PO4 + Ca(OH)2 -> H2O + Ca3(PO4)2
