Short answer
more short answer quesitons
100
two or more materials stirred together
What is a mixture?
100
characteristic of an object, something you can observe
What is property?
100
of the solutes we worked with, this solute is more soluble than salt
What is citric acid?
100
we completed this process by using screens, filters and evaporation
What is separating mixtures?
100
we used a balance scale, gram weights and a cup of water to do this
What is the way to find out how many grams of a solute (salt or citric acid) is in a solution?
200
the material that dissolves in a solution
What is a solute?
200
causes liquids to dry up, the liquid turns to gas and disperses into the air, leaving any dissolved material behind
What is evaporation?
200
although we did not taste it in class, this solute has a sour taste
What is citric acid?
200
evaporation will only work for separating either of these solutions we created
What is salt or citric acid?
200
this solute is about 3-4 times more soluble than salt
What is citric acid?
300
process in which one material disperses uniformly into another so that it seems to disappear
What is dissolving?
300
special mixture formed when a material dissolves in water
What is a solution?
300
after adding about 10-15 grams of this solute to our 50 ml of water, we had a saturated solution
What is salt?
300
this solution is considered the universal solvent
What is water?
300
historically, this was important to people in early times for flavoring and perserving foods
What is salt?
400
the liquid part of a solution
What is a solvent?
400
a scientific drawing or illustration
What is a diagram?
400
after adding about 45-65 grams of this unknown solute, we saturated the 50 ml or water
What is citric acid?
400
square shape with an "X" in the middle
What is the pattern in an evaporated salt crystal
400
this gas is responsible for decompression sickness that sometimes affects deep sea divers
What is nitrogen?
500
solid form of a material that can be identified by its properties such as shape and pattern
What is a crystal?
500
when the solute you are adding to water no longer dissolves into the solution
What is saturation?
500
there are about 92 of these found naturally on earth (hint: think periodic table)
What are elements?
500
this kind of solution will weigh more than one that is not saturated
What is a saturated solution?
500
a solution reaches this when a solute can no longer dissolve in the solution it is being added to
What is a saturated solution?
