Dissolve:
To mix one type of matter into another type of matter to form a solution
Solvent:
Solute:
The larger part of the solution
The smaller part of the solution
Dissolving:
Pollution:
Soluble:
Un soluble:
Mix completely with a solvent to form a solution
Contaminants in the environment that can harm living things
Able to dissolve in a specified solvent
Unable to dissolve in a specified solvent
Concentrated solution:
Dilute solution:
Concentration:
A solution with a large amount of solute in a given volume of a solution
A solution with a small amount of solute in a given volume of a solution
The amount of solute present in an amount of solution
Saturated solution:
Unsaturated solution:
Solubility:
A solution where no more solute can dissolve
A solution where more solute can dissolve
A measure of how much solute can dissolve in a certain solvent to become a saturated solution at a particular temperature and volume
Solution:
What is the difference between a solution, solute, and solvent?
What are some solid, liquid, and gas solutions?
A mixture that contains a solute and solvent
A solution is, A mixture that contains a solute and solvent, a solute is, The smaller part of the solution, and a solvent is the larger part of the solution.
A solid solution can be aluminum alloys, a liquid solution can be apple juice, and a gas solution can be air.
Concentrated vs Dilute:
Ways to increase or decrease solubility of a solute
Saturated vs unsaturated
Dilute solution: A solution with a small amount of solute in a given volume of a solution
Concentration: The amount of solute present in an amount of solution
Increase or decrease in temperature
Increase or decrease in temperature
Saturated solution: A solution where no more solute can dissolve
Unsaturated solution: A solution where more solute can dissolve
Soluble vs insoluble
3 examples of common solvents and solutes:
Soluble: Able to dissolve in a specified solvent
Un soluble: Unable to dissolve in a specified solvent
Water
Ethanol
Acetone
Toluene
Solutes
Salt
Sugar
What can you do to make a sugar cube dissolve faster?
Increase the temperature
Continuous stirring
What are the solvents and solutes in maple syrup?
Water is the solvent and sugar is the solute.
The tea contains 96% water, 3% sugar and 1% salt. What are the solvents and solutes?
Water is the solvent, and sugar and salt are the solutes.
Why is water a universal solvent?
Water dissolves more substances than many in the world
Ellie dissolve 50ml of sugar and 150ml of water. It comes out to 170ml. Ellie is surprised.
Why is Ellie surprised?
150 ml and 50 ml adds up to 200ml
The sugar dissolved in, only adding a bit of ml.
our teacher gives you a salt solution, how do you know if it is saturated?
Saturated means that the solute can’t be mixed in anymore, so mix in some salt and if it doesn’t dissolve, it is saturated.
If you continuously mix sand and water, will it mix?
No, this is because sand is insoluble and will sink to the bottom.
If you mix sugar into water until it can no long dissolve, is it concentration, Saturation, or both?
It is saturation and concentration.
Matt says concentration means only a lot people in a pool and dilute is a few. Is he correct?
The people represent solute particles, and the water represents solvent particles
The solubility of sugar and water is 204g/100ml at room temperature.
How much will dissolve at 100 and 2000 ml?
204g and 4080g
Malcolm added 108g of salt into 300 ml of water. What is the solubility.
The solubility is 36 because 108/3 = 36
Instead of adding 1 tsp of salt a chef adds 1 tbsp. What can he do to reduce the saltiness? What are some effects?
You could add more water to the soup. But this could make your soup waterier rather than thick which is an effect.
