WHAT IS THE DEFINITION OF SOLUTION?
when one thing is dissolved into another
100
WHAT IS THE DEFINITION OF SATURATED, UNSATURATED AND SUPERSATURATED?
1. Saturated - nothing more can be dissolved
2. Unsaturated - more solute can be dissolved
3. Supersaturated - holds more solute than normal due to the higher temperature

WHAT MAKES A STRONG BASE?
Lots of Hydroxide Ions = Strong Base

WHAT IS THE DEFINITION OF CHEMICAL PROPERTY?
Material actually reacts to become something else
- Burning
- Corroding
- Oxidizing
- Bubbling
200
FACTORS THAT AFFECT SOLUABILITY
- Temperature

1. WHAT IS THE LAW OF CONSERVATION OF MATTER?
2. WHAT IS THE KINETIC THEORY OF MATTER?
1. You can not create or destroy mass only change it
2. All matter is made of matter, which are in random motion
400
WHAT IS THE DEFINITION OF INDICATOR AND PH?
Indicator- a chemical that changes color in the presence of an acid or a base
pH- the concentration of H + ions; the more positive ions the more acidic the less positive ions the more basic

WHAT IS THE DIFFERENCE BETWEEN PHYSICAL AND CHEMICAL CHANGE?
Physical Change is the change in appearance and shape while chemical change is when a material actually becomes something else
500
DIFFERENCE BETWEEN SOLUTE AND SOLVENT
Solute is what is being dissolved
Solvent the substance doing the dissolving

STATE ALL YOU KNOW ABOUT DENSITY
Definition - how compact something is
Formula - mass/volume
Density less than one floats
Density more than one sinks
