Red Unit x2 (9) - Solutions Flashcards
Immiscible solution
Two liquids that don’t mix
Usually present in a larger amount, used to dissolve solute in
Solvent
Forms when a solute dissolved in a solvent
Solution
The substance that is being dissolved
Solute
A solution that contains ions and conducts electricity
Electrolyte
More solute can be dissolved
Unsaturated
The max amount of solute is present
Saturated solution
There is too much solute
Super saturated solition
Why is water polar
Water molecules have 2 opposite charged regions, positive hydrogen and negative oxygen
What charge is O
-
What charge is H
+
What forms in supersaturated solutions
Crystals
The max amount of solute at a given temperature
Solubility
Diluted solutions have ____ solute dissolved in ______solvent
Small, excess
Concentrated solutions have ____ solute and ____ solvent
Excess, small
Mixture where you can identify individual parts and is easily separated
Heterogeneous mixture
Positive ions are attracted to (what is water)
Negative O
Solutions are ——— mixtures
Homogeneous
Solution where the solvent is water
Aqueous solution
Water is referred to as the Universal Solvent because..
- it is POLAR
- Oxygen has a negative charge, hydrogen a positive charge.
- Oppusites attract
- Water is like a magnet, pulls on electrisally charged Hings
Does wax really repel water?
No. H2o is more attracted to itself than wax, and wants to stay with other similar paricles.
Forms because water pulls in itself
Surface tension
Cohesión
Same molecules attracted to one ankther
Adhesión
One substance attracted to another substance
