Final Jeopardy

Math!

Final Jeopardy1x10-10 – water is neutral, therefore has pH of 7

1000=10x10x10=103 means change of 3

More basic so pH =7+3=10

pH 10 means [H+] = 1x10-10

A substance 1000x more basic than water would have

what [H+] concentration?

$200

What is a base? (Number 12 on review)

This type of substance is generally slippery and

releases OH- in solution.

$400

What are acids? (Number 11)

These substances taste sour.

$600

What are bases?

These substances generally taste bitter.

$800

What are both acids and bases (Numbers 11 and 12 on review)

These substances are good electrolytes.

$1000

What are acids?

These substances release H+ ions in solution.

$200

What is weak? (Number 4)

This type of acids and bases partially dissociate in water.

$400

Mg(OH)2 + H2SO4 MgSO4 + H2O

Base Acid Salt Water

(Number 1)

Identify the parts of the following neutralization reaction:

Mg(OH)2 + H2SO4 MgSO4 + H2O

$600

What is strong?

This type of acid or base completely disassociates in

water.

$800

Water and a salt.

These are the products when an acid and a base react

together.

$1000

What is double replacement? (Number 2)

Neutralization reactions are this type of reaction.

$200

What are bases? (Number 5)

These substances turn red litmus paper blue.

$400

What are acids (number 6)?

These substances turn blue litmus paper red.

$600

10 (Number 8)

A solution with a pH of 14 is how many more times basic than a solution with a pH of 13?

$800

How should you make an acidic solution? a. add acid to waterb. add water to acidc. add both at the same timed. you should never make an acidic solution because

it’s too dangerous

A (Number 27)

$1000

Draw the pH scale. Label the following: The range of pH’s shown on the scaleWhere a neutral solution would beWhere the strongest acids and strongest bases would be

$200

a) base b) acid c) acid d) acid

Number 9 a-dIdentify each of the following as acids

or bases:

a) NaOHb) HClc) HFd) HNO3

$400

e) base f) base g) acid h) base

(Number 9:e-g)

Identify each of the following as an acid or base:

e) Al(OH)3

f) KOHg) HIh) NH4OH

$600

Sour / high

If you ever tasted HCl(which you wouldn’t because you are smart), it would most likely

taste _____ and have a _____ concentration of H+ ions.

$800

Slippery / low

Calcium hydroxide feels _________ and has a _____ concentration of H+ ions.

$1000

Al+3(OH)-1

Al(OH)3

What is the formula of Aluminum hydroxide?

$200

pH = 6.44 pOH=14-6.44=7.56

What are the pH and pOH of a solution with a [H+] of 3.64 x 10-7?

$4000.26 mol/0.457 L = 0.57 M

pOH =-log[0.57] = 0.24

What is the pOH of a solution in which 0.26 moles of

sodium hydroxide (NaOH) was dissolved in .457 L of

water.

$600

1000

A solution with a pH of 4 is how many times more acidic than a solution with a pH of 7?

$800

# [H+] pH A/B/N1 8.91 x 10-4

2 7

3 2

4 1x10-11M

Complete the following table:

# [H+] pH A/B/N1 8.91 x 10-4 3.05 Acid

2 1x10-7 7 Neutral

3 1x10-2 2 Acid

4 1x10-11M 11 Base

Number 13!

$100010000 = 10x10x10x10 = 104

Means a change in pH of 4, so it has pH of 5

What pH would a substance that is 10000x more acidic than one with a pH 9 have?

$200

Strong Base (Number 18)

If calcium hydroxide completely dissociates into

positive and negative ions in water, then it is a _________.

$400

If HC2H3O2 partially dissociates in water, then it is a

_______________________.

Weak acid. (Number 19)

$600

True/False/False/True (Number 24)

True or False? _____Strong acids almost completely dissociate in water while weak acids partially dissociate in water._____Strong acids partially dissociate in water while weak acids almost completely dissociate in water. _____Weak acids always have a lower pH than strong acids._____Strong acids produce hydroxide ions in solution and weak acids produce hydronium ions in solution.

$80010.3 M NaOH (Number 25)

Which solution is more concentrated, 10.3 M NaOH or 7.5 M HCl?

$1000

Strong – brightweak – dim,

non – turned off(Number 26)

What happens to a light bulb connected to an aqueous solution when you have a strong electrolyte? Weak electrolyte? Nonelectrolyte?
