finding concentration
The amount of solute that is dissolved in a given solvent is described as...
concentration
The amount of matter in a given volume is describing... (AKA how much "stuff" is in a space)
density
If a solution has dissolved all of the solute it can into a given solvent, then it is...
saturated
If I have 5 grams of salt, how many mL of salt do I have?
5 mL
What does heating do to solute particles?
It helps them dissolve.
A solution in which more solvent has been added has been...
diluted
What is the equation for calculating density?
density = mass/volume
Do all substances have the same saturation?
NO, every substance is different/unique
I have a cup with 50 mL of water. I add 10 mL of sugar to the cup. How much will it weigh now?
50 g + 10 g = 60 g
What is the quality that determines how much solute will dissolve?
solubility
Which of these two solutions is the concentrated and diluted one?
-50 mL of lemonade powder and 200 mL of water
-50 mL of lemonade powder and 500 mL of water
50:200= concentrated
50:500 = diluted
An object sinks because it is __________ dense than the water, but will float if it is ___________ dense than the water.
more, less
What could you do to figure out if your solution has reached the saturation point?
Try adding more solute to the given solvent. If it does not dissolve no matter what you do, then the solution is saturated.
Explain the Law of Conservation of Matter
Matter can neither be created nor destroyed, all matter simply changes forms
Which is more soluble- table salt or Epsom salt?
How do you know?
Epsom salt
It took more to saturate 50 ml of water.
Describe a process you could use to find out which mystery solution, when all the solutions have the same volume has the highest concentration.
If you are building a density tower with different liquids, where will the most dense liquids be? Where will the least dense liquids be?
bottom, top
What can you do to reach saturation faster?
Add heat or stir/shake the solution
Give an example of matter changing forms
physical changes (melting, freezing)
or chemical changes (burning, tarnishing)
What conditions must be met to compare two solutions saturation and concentration
They must have equal volume
You have solution A with 10 grams of salt and 100 grams of water. Solution B has 10 grams of salt and 50 grams of water. What would the concentration be for each? Which one is more concentrated?
A= 1/10
B= 1/5
B is more concentrated (bigger fraction)
I have a mystery liquid with a density of 16 g/mL. It is filling a glass with a volume of 40 mL. What is the mass of this mystery liquid?
HINT: density= mass/volume
16= ?/40
16x40=640 grams
16= 640/40
If you have two solutions made with the same substances, say salt and water. Both are made with 50 mL of water and both are saturated, which one weighs more?
They are the same, saturation point with salt should be the same for both
Which of these solutions, if using the same amount, would have the same wieght as a solution made with 10 grams of sugar and 100 mL of water?
-a solution with 10 grams of sugar and 50 mL of water
-a solution with 20 grams of sugar and 200 mL of water
-a solution with 15 grams of sugar and 130 mL of water
20 to 200
20/200 = 10/100
How do you know a solution is saturated?
There are undissolved particles at the bottom
