- Chapter 21-Substances, mixtures, and
soulubility
- Differences between substances and mixtures
- Substances
- Combounds and elements
- Combounds and elements
- Mixtures
- A Mixture of substances
- Homogeneous mixtures
- Also Known as solotions
- cannot see different materials
Mixed to molecular scale
- can be seperated by chemical means
- can be seperated by chemical means
- cannot see different materials
Mixed to molecular scale
- Also Known as solotions
- Heterogeneous mixtures
- Can see different substances
- Can be seperated by phisical means
- Can be seperated by phisical means
- Can see different substances
- Homogeneous mixtures
- A Mixture of substances
- Substances
- Solution
- Solutes
- Substances that dissoves
- Substances that dissoves
- Solvents
- Dissolves Solutes
- The larger amount in Solution
- State of matter of solution is usually same as the solvent
- State of matter of solution is usually same as the solvent
- The larger amount in Solution
- Dissolves Solutes
- Solutes
- Aqueous solutions have water as the solvent
- Water Molucule
- Water is a Molecular compound
- It can dissolve both ionic and molecular compound
- it dissolve molecular compounds
as a group when it dissolves ionic
bond atom by atom
- it dissolve molecular compounds
as a group when it dissolves ionic
bond atom by atom
- It can dissolve both ionic and molecular compound
- Water is a Molecular compound
- Solubility
- Measure of how much of a
solute can dissolve in a certin
amount of solvent
- Solid - Liquid Solution
- when temp. increases the solubiliy increases
- when temp. increases the solubiliy increases
- Gas- liquid solutions
- When temp. increase the solubiltiy decrease
- When Pressure increases solubility decreases
- When Pressure increases solubility decreases
- When temp. increase the solubiltiy decrease
- Saturated solutions
- a Solution that holds the total amount of solute that can be hold under the given solution
- a Solution that holds the total amount of solute that can be hold under the given solution
- unsaturated solution
- A solution that has not reached its max it can dissolve at the given condisions
- A solution that has not reached its max it can dissolve at the given condisions
- Super Saturated solution
- a solution that has more solute dissolve than it can under a given condision
- a solution that has more solute dissolve than it can under a given condision
- Solid - Liquid Solution
- Measure of how much of a
solute can dissolve in a certin
amount of solvent
- Dissolving Rate
- how quickly a substance
dissolves.
- 3 factors that decrease the dissolve time are
- Temp. (Hot vs cold, hot is faster)
- Partical size(smaller is faster)
- Mixing(more mixing is faster)
- Mixing(more mixing is faster)
- Partical size(smaller is faster)
- Temp. (Hot vs cold, hot is faster)
- 3 factors that decrease the dissolve time are
- how quickly a substance
dissolves.
- bonds
- Covalent Bonds
- Bonds that share e-
- Polar
- Share e- non-evemly
- Share e- non-evemly
- Non- Polar
- Share e- evenly
- Like dissolves like so
polar dissolves polar and
non polar dissolves non
polar
- Like dissolves like so
polar dissolves polar and
non polar dissolves non
polar
- Share e- evenly
- Polar
- Bonds that share e-
- Ionic Bonds
- Bonds created when Atoms gain or loss e-
- This makes them become positive or negative
- So they become attracted to each other
- So they become attracted to each other
- This makes them become positive or negative
- Bonds created when Atoms gain or loss e-
- Covalent Bonds
- Concentration
- how much solute is present in a
solution compared to the amount of
solvent
- Dilute
- a solution that
has a very low
amount of solute
compared to the
amount of
solvent
- a solution that
has a very low
amount of solute
compared to the
amount of
solvent
- Concentrated
- a solution that
has a high
amount of
solute
compared to the
amount of
solvent
- a solution that
has a high
amount of
solute
compared to the
amount of
solvent
- Dilute
- how much solute is present in a
solution compared to the amount of
solvent
- Acid and bases
- refer to chart on worksheet
- refer to chart on worksheet
- pH
- Refer to worksheet (back of acid and base sheet)
- Indicators
- substances that change color relating to pH
- substances that change color relating to pH
- Refer to worksheet (back of acid and base sheet)
- Differences between substances and mixtures
- Chapter 8:Life's Structure and
Classification
