solvents, solutes & solutes x Flashcards
(29 cards)
what do you call a solid that dissolves in a liquid and what happens
soluble and a solution is made
what happens to a substance when it dissolves
it seems to disappear
what is the substance which is dissolved called
solute
what do you call the liquid the substance dissolves into
the solvent
what do solutions look like
they can be colourless or coloured but they are always clear
what do you call a solid that does not dissolve in a liquid and what can you see
insoluble and you can see small particles still floating around in the liquid
what is the most important solvent
water
why is water the most important solvent
because it dissolves so many solutes
why is water the most important solvent
it is safe, cheap and widely available
what is water used most for
washing
what can be added to water to become even more powerful
detergent
what stains can water and detergent not get out
chewing gum, engine oil and nail polish
what solvent can get out engine oil
paraffin
what solvent can get out chewing gum
trichloroethane
what solvent can get out nail polish
acitone
what can solutions be described as
dilute or concentrate
what is a concentrated solution
one that contains a lot of solute in a small volume of solvent
what is a dilute solution
one that contains a small amount of solute in a large volume of solvent
how could you turn a concentrated solution into a dilute solution
add more solvent
how could you turn a dilute solution into a concentrated solution
add more solute
what is a saturated solution
the point at which the solution contains so much solute that it cannot dissolve any more
why is water the most important solvent hat does the saturation point depend on
the temperature of the solvent
what happens as the solvent gets hotter
it can usually dissolve more solute until a new saturation point is reached
how do crystals form
when hot saturated solution cool down
