In a cup of salt water, what is the solute being dissolved.
salt
This term describes a solution that has a small amount of solute relative to the amount of solvent (ex: watery drink).
Dilute
A solution that can still dissolve more solute at a given temperature is called this.
unsaturated
This mechanical action (stirring or shaking) speeds up how fast a solute dissolves in a solvent.
agitation
A pitcher of lemonade is too sour and strong. State the exact action you should take to dilute it.
Add water/more solvent
This term describes any solution where water is the solvent doing the dissolving.
aqueous solution
Adding more solvent to a solution causes the concentration to do this.
dilute
This clear visual evidence shows that a solution has reached a saturated state.
undissolved solid gathering/sitting at the bottom
Besides agitation, name the other two physical factors that increase the rate of dissolution.
Increasing temperature and increasing surface area
A scientist leaves a beaker of saltwater uncovered in the hot sun for three days. As water evaporates, describe what happens to the concentration of the remaining liquid.
the concentration increases
A student dissolves cocoa powder in warm milk. Name the solvent in this mixture.
milk
Container A has 10g of salt in 100mL of water. Container B has 30g of salt in 100mL of water. State which container is more concentrated.
B
You add 1tsp of salt to a beaker of water and it completely disappears after stirring. Name the saturation state.
unsaturated
Beaker 1 is stirred rapidly. Beaker 2 sits completely still. State which beaker will take longer to dissolve equal amounts of salt.
2
A student mixes 5 drops of blue dye into Cup 1 50mL water) and 5 drops into Cup 2 (200mL water). Identify which cup will have the darker shade of blue.
Cup 1
To make a solution non-aqueous, you must change what component to what?
The solvent to something besides water
Bob mixes a flavored drink powder with water and notices it became very dark and sweet. What term is used to describe the solution.
Concentrated
Name two different ways to force undissolved solid salt resting at the bottom of a SATURATED beaker to fully dissolve.
adding more solvent
Explain why crushing a large rock salt crystal into fine table salt makes it dissolve faster.
increases the surface area, exposing more solute particles to the solvent
Chef Ramsey accidentally spills extra salt into his soup. Name the only way he can decrease the salt concentration without removing any actual salt particles.
Diluting by adding more water/broth
What is the solvent used the most
water
Beaker X has 15g of powder in 100mL of water. Beaker Y has 15g of powder in 300mL of water. Explain which is more dilute and why.
Y because it has more water spreading out the same amount of solute
A student adds 50g of solute to water and stirs. 40g dissolves and 10g sits at the bottom. Identify the saturation state
saturated
What does the rate of dissolution mean? It's a fancy way of saying what?
How fast or slow I can dissolve something
The graph below illustrates the solubility of potassium chloride (KCl) in water at a variety of temperatures. At what temperature does 30 g of KCl dissolve in 100 g of water?
10 degrees Celsius
