Soutions are homogeneous mixtures
True
False
The liquid part of the solution is called
Solute
solvent
mixture
substance
the solute is the substance that is dissolved in the solvent
True
False
which technique is used for the separation of solutions
Chromatography
Evaporation
filtration
Sieving
Solutions are couldy (not clear)
True
False
Suspension is a mixtures of two substances that separate if not stirred
True
False
Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid.
True
false
put the stages of water treatement in order
Screening and straining,filtration,disinfection
Disinfection, screening and straining, filtration
Filtration, disinfection, screening and straining.
Why are solutions transparent?
Because they are heterogeneous mixtures in w
because the solid substances become transparent when they dissolve.
because the dissolved substances break down into smaller pieces so the light passes through the mixture
Solutions are not transparent
Soluble sustances are substances that dissolve in the liquid
True
False
Sugar is insoluble in water
True
False
Conservation of mass means
The mass of the solute = the mass of the solution
The mass of the solvent = the mass of the solution
the mass of the solute= the mass of the solvent
the mass of the solute + the mass of the solvent = the mass of the solution
20 g of sugar is stirred in 50 g of tea, what is the mass of the solution
70
80
30
25
The mass of the solute dissolved in a certain volume of solvent is
Solubility
Concentration
solution
density
The more solute is dissolved, the lower concentration is
TRUE
FALSE
There is a limit to how much solute can dissolve in a particular amount of solvent
True
Flase
it depends on the substances in that solution
A solution in which the maximum amount of solute has been dissolved is a
Saturated solution
unsaturated solution
The mass of a solute dissolved in 100g of solvent is
Concentraion
Solubility
Solubility depends on
Temperature
the solvent
the temperature + the solvent
the mass
Solubility increases with temperature
True
False
