1. TAKE OUT YOUR FOLDABLE and NOTEBOOK SO I CAN CHECK IT

2. On BACK: Chapter 9 Study Guide Name Date Period

3. Notebooks page 78-79
A) candle glued & colored correctly- B) all data from page 79
10 observations of candle
calculate change in height & mass
changes in candle statement

4. Describe using words: solute, solvent, dissolve
Box 1: SOLUTIONS

Describe using words: solute, solvent, dissolve

5. 9.1 Water and solutions
A solution contains at least two components: the solvent dissolves a solute.
The solvent is the part of a mixture that is present in the greatest amount.
Which of these is the solvent?

6. Box 2: PHYSICAL AND CHEMICAL CHANGES
Short definition in your own words
Physical: Changes the form /appearance
Not making a new substance
Chemical
Changes it into a different substance
Forms new substance with different properties

7. Acids turn indicators RED Bases turn indicators BLUE
Box 3: ACIDS AND BASES
Acids turn indicators RED
Bases turn indicators BLUE

8. Box 4: How we know when something is Dissolved

description

9. When the solute particles are evenly distributed throughout the solvent, we say that the solute has dissolved.
On the molecular level, dissolving of a solid (like sugar) occurs when molecules of solvent interact with and separate molecules of solute

10. Box 5: DILUTE VS CONCENTRATED
Solution with more solvent and less solute.
Solution with more solute in solvent

13. I. Difference Between Physical and Chemical Changes:
Changes the form /appearance
(Shape, State of Matter- etc.)
Not making a new substance
Chemical
Changes it into a different substance
Forms new substance with different properties

14. II. Evidence of a Chemical Reaction: The Four Deadly Warning Signs!
Bubbles (gas is made)
A solid appears (Precipitate)
Color change
Change in Temperature
KEY: new substances are formed with different properties

Picture/ examples
List 4 properties:
“Strong acids have…”

31. Box 8: ACIDS They taste sour
Properties of Acids
They taste sour
They turn litmus & universal indicator red
All acids form hydronium ions (H+) when mixed in water.
Acids have a pH range from 0-6 (7 is neutral)
Strong acids have more hydronium ions when dissolved in water

32. Picture/ examples List 4 properties: “Strong bases have…” Box 9: BASES
Color pH
Ions
taste
Picture/ examples
List 4 properties:
“Strong bases have…”

33. They turn litmus paper blue.
Properties of Bases
They taste bitter
They turn litmus paper blue.
All bases form hydroxide ions (OH-) in water.
Bases have a pH range from 8-14 (7 is neutral)
Strong bases have more hydroxide ions when dissolved in water

34. Fold your paper: 4 5 6 7 8 9 1 2 3 Inside- draw in the lines
Front- draw in the lines

35. pH 7 = neutral;
pH 0-1 = very strong acid
pH 14 = very strong base
