DEMONSTRATION
Potassium Iodide reacts with Lead(II) Nitrate
?
THINK AND WRITE!
Discuss with your table what just happened using the following
vocab:
• Potassium iodide
•
Lead Nitrate
•
colorless solution
•
pipette
•
small test tube
• Precipitate
• Reactants
• products
SAMPLE PARAGRAPH
1.
Colorless solutions of Potassium iodide and lead (II) nitrate are the
reactants.
2.
The teacher used a pipette to put an amount of potassium iodide
in a small test tube.
3.
Then she used another pipette to get some lead nitrate and add it
to the 1st solution.
4.
As the two solutions reacted, a bright yellow precipitate formed.
This precipitate is a powdery solid and will gradually sink to the
bottom of the test tube.
5.
It is one of the products of the chemical reaction
STANDARDS COVERED

changes
PHYSICAL CHANGE
•
Texture
•
Temperature
•
Shape
•
Change of State (Boiling Point and Melting Point are significant factors in
determining this change.)
CHEMICAL CHANGE
•
Change in Temperature
•
Change in Color
•
Noticeable Odor (after reaction has begun)
•
Formation of a Precipitate
•
Formation of Bubbles

THE NATURE OF MATTER
Unit 1!
SOME DEFINITIONS
Physical State- the three states of matter are solid, liquid,
and gas
BELL WORK FOR AUGUST 13/14
1. A. Draw Diagrams to show the arrangement of
particles in:
(i) Solid lead
(ii) Molten lead
(iii)Gaseous lead
b. Explain how the particles move in these three states of
matter
HEATING CURVE EXPLANATION
http://www.alchemical.org/thermo/other/heatingcurve.swf
KINETIC THEORY
1.
All matter is made up of tiny, moving particles, invisible to the
naked eye. Different substances have different types of
particles (atoms, molecules or ions)
2. The particles move all the time. The higher the temperature, the
higher they move, on average.
3. Heavier particles move more slowly than lighter ones at a given
temperature.
SOLID
• Particles only vibrate about fixed positions
• Have a regular structure
• X-ray crystallography can confirm how particles in a solid are
arranged
LIQUID
• Particles have some freedom and can move around each other
GAS
Particles move freely and at random in all the space
available. Collide less often than in liquid.
WORKSHEET 2.3
Missing sentence from last question:
Water particles are attracted to the salt particles in the
crystal and surround the salt particles
