Does an acid have a conjugate acid or conjugate base?

Conjugate base

300

Identify the acid in the following equation:

HA + B ----> A^- + BH⁺

HA

400

Identify the conjugate base in the following equation:

HA + B ---> A^- + HB⁺

A^-

500

What are two properties of acids?

They conduct electricity

They react with metals

Generate hydronium ions (H₃O⁺)

Mostly liquids or gases

Donate protons

Bases

100

Do bases accept or donate protons?

Accept

200

Does a base have a conjugate acid or a conjugate base?

Conjugate acid

300

Identify the base in the following equation:

H₂X + BH ---> H₃X⁺ + B^-

H₂X

400

Identify the conjugate acid in the following equation:

H₂X + BH ----> H₃X⁺ + B^-

H₃X⁺

500

What are two properties of bases?

They generate hydroxide ions (OH^-)

They often feel slippery

Mostly gases

Accept protons

pH

100

What is the range of pH values?

0 to 14

200

What pH's are acidic?

Anything below 7

300

What is the [H₃O⁺] for a solution with a pH of 10.38?

4. 16 x 10^-11 M

400

What is the pH of a solution with a [H₃O⁺] of 4.2 x 10^-3?

2.38

500

What is the pH of a solution that has a [OH^-] concentration of 4.55 x 10^-2

12.66

Titrations

100

When your titration is complete, what should the pH be?

Neutral (7)

200

What do they call the point in which the titration is complete?

The equivalence point

300

What is the solution called that has a known concentration?

Titrant (standard solution)

400

Generally describe the process of a titration.

You slowly add titrant to the flask containing the solution with the unknown concentration until it reaches the equivalence point. 

500

What is the concentration of a solution if you added 16 mL of titrant with a concentration of 0.2 M to 10 mL of the solution with the unknown concentration?

0.32 M

WILD!

100

What are two ways in which you can measure pH?

Indicators or pH meters

200

What is the K_W equation?

K_w = [H₃O⁺] [OH^-]

300

What can buffer solutions do?

They can resist changes in pH

400

If the concentration of [OH^-] is 2.38 x 10^-4, what is the concentration of [H₃O⁺]? 

4.20 x 10^-11 M

500

What is the difference between a strong and weak acid?

Strong acids completely dissolve into its ions and there is no reverse reaction; weak acids only partially dissolve into its ions and there is a reverse reaction.
