Separating Mixtures
The two parts that make up a solution
Solute (Solid) and Solvent (Liquid)
The process of melting
a solid becoming a liquid through heat energy
Is a soft drink a solution?
Yes
How can you tell when a solution is saturated?
When the undissolved solute is laying at the bottom.
What is evidence of a chemical reaction?
Formation of gas or precipitate (a new solid substance)
The device used to separate salt solution from powder
filter paper
What happens to the salt particles size when they dissolve?
They break down into smaller pieces
The definition of concentration
Is the amount of dissolved material per unit volume of water.
If none of the solute dissolves it is _____
Insoluble
Is A or B a chemical reaction? A- Different kinds of food getting mixed in your stomach B- When you eat, some foods make you burp
B- When you eat, some foods make you burp
Do all solid materials dissolve in water?
No
What happens to the icecube particles size when it melts?
They remain the same size
How can you dilute a concentrated solution?
Add water
What is solubility?
is the property that indicates how readily a solute dissolves in a solvent.
What is a Product?
How do you separate a salt solution?
Use an evaporation disk
What is the difference between dissolving and melting?
Dissolving occurs when one substance (solute) is broken down into smaller pieces until the pieces are no longer visible. It involves two substances.
Melting is the change of phase from solid to liquid in a single substance caused by heat.
How do you compare concentrations?
Create equal volumes and find the mass. The heavier one is more concentrated
You have two saturated cups of kool-aid with equal volumes. Solution A has 4 spoons of sugar and Solution B has 7 spoons of sugar. Will they taste the same or different?
They will taste the same
What are reactants?
Reactants are the original starting substances.
