acids bases and salts
ACIDS BASES
AND SALTS
ACID + BASE --> SALT + HOH
H-anion + cation-OH --> cation-anion + HOH
Neutralization
Acids release
H+ ions in
solution with water
Bases release OH- ions
in solution with water
The word “acidity”
refers to the concentration of
Hydrogen ions
H+ in solution. If there are more H+
Ions, then
the solution is more acidic!
The word “basic”
refers to the concentration of
Hydroxide ions
or OH- in solution. If there are
more
OH- ions,
the solution is more basic!
Acids
absorb hydroxides to neutralize a base
Bases
absorb hydrogens to neutralize an acid.
pH SCALE
A pH scale
is a way of measuring the
Concentration
of hydrogen ions in solution.
The scale
goes from 1 to 14
1 2
3 4 5
6 7 8 9
10 11 12 13
14
very neutral very
acidic basic
Acids have a pH of less than 7
Bases have a pH
of more than 7
pH 7 is H+ = OH-
every stage on the pH scale is a 10fold increase
so pH 7 has 102 more Hydrogens than pH 9.
Pure water is pH
7
Milk is pH 6
Lemons are pH2
or 3
Bleach is pH 12
Baking soda is pH
9
pH indicators
Some things change colour in the presence
Of an acid or a base
For example
Cabbage juice will turn pink for acid, blue for base
Litmus paper will turn pink for acid, blue for base
Phenolphthalein will turn pink for base and clear for
Acid
Bromothymol blue will turn blue for base and
yellow for acid
Universal indicator will turn many different colours

presentation is out of 5. for 5/5 it is typed with illustrations or photos and emailed to msngscience@gmail.com. for 4/5 it is pretty good but there are a few spelling mistakes. for 0-3 out of 5 it is in pencil or messy
10
Clear writing is out of 10. for 9/10 or 10/10, it is written with no English mistakes and it clearly communicates each part of the lab report. 7-8/10 it is very well written for 5-6/10 some parts are not so clear and the reader must guess what you are trying to say. 0-4/10, it is minimally communicating what happened
10
Paragraphs are insightful and your observations are well done. this is out of 10.
9-10/10, your observations and conclusions are well written and logical. It is brilliant
7-8/10 your observations and conclusions are very well done
5-6 your conclusions don't really logically follow from your results
0-4 your conclusions are not relating to your results at all
ACKNOWLEDGEMENTS
write all names and who contributed what including the % of their contribution. so two people who contributed equally would be50%

Drawing Lewis Structures of Ionic Compounds
Next day we will try drawing lewis structure of covalent compound. Here are the practice problems for those

practice practice practice
Recall that worksheet Chemistry practice sheet and the Chemistry practice sheet key. This was given for homework and you will be tested on this soon.
if you are done that, then there is another worksheet on types of reactions:
worksheet. Here is the answer key for types of reactions. Please write out these answers in your notebook and show me when done for work period marks. There is a typo on this one:
Section 2 number 3 has a typo on answer key. The co-efficients should be...4, 5, 4,6 and not what they have on the key
Number 3 section 3 is 1,2,2

Types of Chemical Reactions
Chemical
reactions may be categorized as follows
1.
Synthesis
2.
Decomposition
3.
Single replacement
4.
Double replacement
5. Combustion
6. Oxidation of metals
A Synthesis reaction:
element +
element --> compound
Decomposition reaction:
Compound --> element +
element
Or
Compound --> smaller compound + element
DOUBLE REPLACEMENT
single replacement
Combustion
Carbon based
fuel + oxygen --> carbon dioxide + water
+ heat and light energy
Cell respiration looks like combustion,
BUT IT IS
NOT. YOUR CELLS ARE NOT COMBUSTING
IN THE MITOCHONDRIA
Glucose + oxygen --> carbon dioxide + water + energy for cell
Oxidation reaction
Metal + oxygen --> metal oxide
ACID BASE REACTIONS ARE ALL NEUTRALIZATION REACTIONS
Metal + oxygen --> metal oxide
ACID BASE REACTIONS ARE ALL NEUTRALIZATION REACTIONS

You will create safety rules by reading and summarizing the safety procedures in your text. Then you will take the Finn Laboratory Saftey Test
The rules can be under the following categories:
HIGHEST PRIORITIES:
THESE RULES CAN BE SUMMED UP LIKE THIS
Talk to the instructor
KEEP ORGANIZED AND SAFE
Keep the classroom safe
Keeping your work area safe
Keep safe with your colleagues
Keep yourself safe
KNOW THE SYMBOLS
Know the correct symbols, WHIMIS symbols
COMMUNICATE AND REACT TO AN EMERGENCY
Emergency procedures for fire, toxins, spills, and evacuation
SAFETY ASSIGNMENT: I divided you into groups and talked about WHMIS. Make a poster of the 20 safety rules which I handed out in class.
Your group must draw a comic showing all the safety rules on one side of the page. put numbers to show where the rule is being applied.
RUBRIK: out of 10
YOUR POSTER IS COMPLETE SHOWING ALL 20 RULES 5 marks
it is missing a few of the rules 2-4 marks
the poster is neat and organized and easy to read 3 marks
it could be better organized and not so cluttered 1-2 marks
the poster is remarkably artistic and creative and is different in some way 2 marks
the poster is very well done and artistic 1.5 marks
the poster is artistic 1 mark
