Solutions Vocab 1
Is water a solute, solvent or solution?
Solvent
The ability of to dissolve a substance in another.
What is solubility?
No need to think too hard. This is when your solution has a large amount of solute to solvent.
What is concentrated?
Process of a solute breaking apart and spreading out evenly in a solvent to form a solution.
Dissolution
Is sugar a solute, solvent or solution?
Solute
This happens when you add more solvent to a solution.
What is it becomes dilute?
liquids that can dissolve in each other like methanol and water, do not dissolve and create VISIBLE seperation
What is insoluble?
Dilution is when you add more _______ to the solution, making it less concentrated.
solvent (most notably water)
Calculate the concentration of solute in the following solution: 20.0 mL of methyl alcohol is dissolved in enough water to make 475 mL total of solution.
Volume/volume calculation
20 mL/475 mL= .0421 x 100 = 4.21%
Used as a general term for a homogeneous mixture of 2 or more atoms, ions, or molecules.
What is a solution?
Increases the rate of dissolution by moving particles is called...
Agitation (stirring)
Where did Mr. Whiting go to college?
Georgia College or Relay University
Describe 1-2 ways a solute may dissolve faster
1) higher temperatures give solvent particles more energy, causing more frequent and energetic collisions with solute particles.
2) smaller particles have more surface area in contact with the solvent, allowing them to dissolve faster.
3) Stirring or agitation increases the rate of dissolution by moving particles around and helping solute and solvent interact more often.
A chemist dissolves 5 mL of ethanol in enough water to make 100 mL of solution. What is the percent concentration of ethanol?
Volume/volume calculation
5 mL/100 mL= .005 x 100 = 5%
Salt dissolving in water makes the salt ____ in water?
What is soluble?
___________ is a homogeneous mixture where one or more solutes are dissolved in a solvent.
What is solution?
Oil and water are said to be this with regard to each other.
What is insoluble?
If you change the 1) ______ 2) ________ or 3______ then this will chang how the solute dissolves...
Temperature, stirring, or size
A sugar solution has 8.5 g of sugar dissolved in 250 mL of solution. What is the percent concentration of sugar?
Mass/volume calculation
8.5 g of salt/250 mL of solution = .034 =3.4%
"Like dissolves like" refers to this molecular property?
What is polarity?
Is apple juice a solute, solvent or solution?
Solution
What is a cell?
collide, evenly
A saline solution is made by mixing 37 g of salt (NaCl) dissolved in 317 g of water. What is the percent concentration of salt in the solution?
Mass/ mass calculation
37g of salt/354 grams of solution = .105 = 10.45%
