Topic 2 Lesson 1-Mixtures and Solutions

made of two or more substances that are together in the same place, but their atoms are not chemically combined

mixture

one that features distinct components that can be easily identified and distinguished throughout the mixture

heterogeneous mixture

a bowl of salad is an example of a heterogeneous/homogeneous mixture

heterogeneous mixture

components are not spread out evenly throughout the mixture

heterogeneous mixture

mixtures often look the same throughout the entire mixture

homogeneous mixture

saltwater, honey, and soy sauce are all examples of heterogeneous/homogeneous mixtures

homogeneous

mixtures of different size particles can be ___________

filtered

magnetic components can be separated by a __________

magnet

___________ mixtures can be heated until some components evaporate and others left behind as solids (an example of this is saltwater)

liquid

a heterogeneous mixture, has small undissolved particles that do not separate or settle

colloid

milk is an example of what

colloid

too small to see, but big enough to scatter light

particles

paint, whipped cream, fog, and smoke are examples of what

colloids

a mixture with particles that can be seen, easily separated by settling

suspension

oil + vinegar salad dressing and muddy water are examples of what

suspension

homogeneous mixture of a solvent and has one or more solutes and has the same properties throughout a mixture in which one substance is dissolved in another

solution

grape juice is an example of what

solution

the part of the solution that is the largest amount, it dissolves the other substance

solvent

substance that is dissolved by the solvent

solute

ex: in grape juice, water is the _______.

solvent

ex: in grape juice, sugar and the other ingredients are the _________

solutes

air is a ______; which is a mix of oxygen, nitrogen, and other gases

solution

in air, nitrogen is the ______ because it makes up most of the air

solvent

stainless steel is a solid ______; which is a mix of iron, chromium, and nickel

solution

___________ break up into individual molecules in water

molecular compounds

table sugar is an example of what

molecular compound

_______ is important to dissolving

polarity

most non-polar molecules (do/do not) dissolve in water

do not

table salt is made of a(n) __________; salt dissolves in water

ionic compound

_______ raise the boiling point of a solution above the solvent

solutes

__________, __________, and ____________ are physical properties of solutions that are affected by concentration

boiling point, freezing point, and density

a concentrated solution will have a lot of ________

solute

the measure of how much solute will dissolve in a solvent at a given temperature

solubility

a solution that can no longer dissolve a solute is __________

saturated

as the temperature increases, the solubility of gases ______ (for example air)

decrease

as the temperature increases, solids become more ______

soluble

_______ is raising the temperature of the solvent increases the solubility of a solid solute

temperature

affects the solubility of gases, has little effect on the solubility of solids

pressure

________ can affect the carbonation in a soda

temperature

carbon dioxide is less soluble in ______ temperatures

warm

ex: a cold soda would have (more/less) carbonation than a warm one would
