AFTER I DISSOLVED SOME SOLUTE IN A SOLVENT I NOTICED THAT NO MORE WOULD DISSOLVE. HOW COULD I DETERMINE IF I HAVE A SATURATED SOLUTION?
Give all the special characteristics of a solution. There should be 4. If you get 3 out of the 4 you get all points.
I made a solution by putting 30 grams of solute into the solvent. I evaporated the solvent in a solution. How much solute will be left?
State all the evidence something has to have to be called a mixture? If you get 2 out of 3 you get the points.
I combine a solute and a solvent. After stirring the solute is at the bottom of the solvent. Have I made a mixture and a solution or both?
Give two things beyond having 2 or more substances and being able to separated that solutions have to make them special mixtures.
I add pepper to water. The pepper stays on the top of the water even after stirring. Is this a mixture, solution or both?
These solutions were compared for concentration. Which is more concentrated? Explain
solution 1 - 50 ml. of water 15 grams of sand solution 2 - 50 ml. of water and 10 grams of sand
SUE MIXED TOGETHER 7O ML OF SOLVENT AND SOME SOLUTE. IT CREATED A SOLUTION. SAM MIXED TOGETHER 60 ML OF THE SAME SOLVENT AND SOME SOLUTE. WHEN HE PLACED THEM ON A BALANCE THEY FOUND THAT SUE'S WAS MORE CONCENTRATED. IS THAT TRUE? EXPLAIN
False
False, you cannot see them in solutions.
YOU COULD ADD MORE SOLVENT TO SEE IF YOU COULD GET THE REST OF THE SOLUTE TO DISSOLVE.
LITERS, MILLILITERS, DECALITERS, CENTILITERS, HECTOLITERS, KILOLITERS, DECILITERS
SOLUBLE
True
False, using evaporation they can be separated.
FILTER OUT THE UNDISSOLVED SALT.
SATURATE SOLUTION
dissolving, solvent and solute, evaporation, cannot see individual parts
true
by 25 grams
30 grams
made of two or more substances, can be separated back into separate substances, can see individual parts
No, just a mixture was made.
dissolving, cannot see individual parts
It is just a mixture.
INSOLUBLE
90 grams
Neither is more concentrated because they are not solutions. Sand and water will not make a solution.
GRAMS, MILLIGRAMS, DECAGRAMS, CENTIGRAMS, HECTOGRAMS, KILOGRAMS, DECIGRAMS
WE DO NOT KNOW BECAUSE THEY DID NOT COMPARE EQUAL AMOUNTS OF THE EACH SOLUTION.
solution
The solute would be floating or go to the bottom of the cup or you could see the individual parts. No dissolving would have occurred.
