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

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.

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)

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

$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

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 _________.
