Flashcards in Acid And Bases Deck (41):
1

Tastes sour

Acid

2

Above 7

Base

3

Low ph

Acid

4

Has a chemical formula that begins with H

Acid

5

Monatomic ions

Only have one element

6

Polyatomic ions

Have more than one element

7

Changes litmus to red

Acid

8

Naming monatomic acid

Put hydro
Then second element name with ic
End with acid
Ex.
Hydrosulfuric acid

9

Naming poly atomic acid

No hydro
if ends in ate, use ic
If doesn't end in ate, use ous
Ex. Nitrite ---- nitous
Nitrate-----nitric

10

Accept hydrogen ions

Bases

11

Ph greater than 7

Base

12

Feels slippery

Base

13

Blue litmus

Base

14

Only works with phenylthalene

Base

15

Naming based

Write cation (metal )
Then anion ( hydroxide) OH
Ex
Sodium hydroxide
NaOH

16

What do the subscripts indicate in a transition metal formula for bases

When it's of OH it indicates the Roman numeral

17

If cation is a transition metal what do you add

Roman numerals

18

Is rain naturally acidic?

Yes
Ph of natural rain water is 6

19

What forms carbonic acid

H2O + CO2
H2CO2

20

Acid rain forms when blank are added to the air by blank

NOx SOx
Burning fuel

21

What neutralizes lakes

Limestone

22

What is the formula for limestone

Calcium carbonate
CaCO3
Acts as a base

23

What kind of lakes don't neutralize

Granite bottoms
Ph become as low as 2 which could burn the skin

24

What is NOx and where does it come from

Nitrogen oxides
Car exhaust and factories

25

What is SOx and comes mostly from where

sulfur oxide
Burning coal

26

NOx + H2O =

Nitrous Acid/ nitric acid

27

SOx + H2O =

Sulfuric acid

28

Acid rain can be a ph of

4

29

Carboxylic acids

Formed by adding carboxyl group
Adding the group makes any molecule carboxylic acid
^ contains 1C 1O and 1 OH
Called fatty acids

30

Below 7

Acidic

31

Recognizing acids

Begins with H

32

Recognizing bases

Ends in OH

33

Will act as a donor

Acid

33

When naming acids first look to see

If they are monoatomic and polyatomic

35

Name HNO3
Hydrogen
Nitrate

Nitric acid

36

H2SO4
Hydrogen
Sulfate

Sulfuric acid

37

H2CO3
Hydrogen
Carbonate

Carbonic acid

38

HBr
Hydrogen bromine

Hydrobromic acid

39

How do you write the formulas when given the name

1) look for hydro meaning mono so it's hydrogen and one other, then find charges and make the formula neutral
Ex hydrochloric= hcl
2) look for ic or ous, means poly and ic means ended in ate, ous means anything else. Find the element/ion then make it neutral
Ex. Sulfuric (ate) acid= h2(so4) -2

40

How do you know how many hydrogen a to put for formulas

You have to make it neutral so look at the charge

41

Name HCL
Hydrogen chlorine

Hydro choleric acid
