Mixtures and Solutions

QuestionAnswer
What happened to the salt when you put it in the water? It dissolves
What happen to the level of the water when you add a solute? The water level rises
How do you know when no more salt will dissolve in the water? Undissolved salt will settle at the bottom
Is undissolved salt at the bottom a part of a solution? No
What is the solution called when there is undissolved salt at the bottom of a cup? A saturated solution
How can you find out if Epsom salts dissolves in water to make a solution? Put it in water to see if it disappears and the solution becomes transparent
How can you find out how much Epsom salts is needed to saturate 50 mL of water? Follow the same procedures used to determine salt saturation
Which is more soluble? Kosher salt or Epsom salt? Epsom Salts
What was the mystery substance on ISN page 77? Citric Acid
How did you come to that conclusion that the mystery substance was citric acid ? Conducted an investigation, then compared the results to the Solubility Table on page 77 of the ISN
Which of the three (Kosher salt, Epsom salt, Citric acid) is most and less soluble? Citric acid is most soluble; Kosher salt is least soluble
Is a soft-drink a mixture or a solution? Both, it is a mixture because it can be separated; it is a solution because it is transparent, and the solute is evenly distributed in the solvent
What is a solvent? Liquid
What is a solute? Solid (Soft-Drink powder)
How could you test to confirm it is a solution? Filter it; check to see if it is transparent
How do you make a concentrated soft-drink solution? More powder (solute), less water (solvent)
How do you make a dilute soft-drink solution? Less powder (solute), more water (solvent)
How can you tell if a soft-drink solutions is more concentrated? Taste, color
Solution A contains 1 spoon of salt and 50 mL of water; Solution B contains 3 spoons of salt and 50 mL of water. Which solution is more concentrated? Solution B
Solution X contains 2 spoons of salt and 50 mL of water; Solution Y contains 4 spoons of salt and 50 mL of water. Solution Z contains 6 spoons of salt and 150 mL of water. Which two solutions are the same? Solution X and Z
Solution X contains 2 spoons of salt and 50 mL of water; Solution Y contains 4 spoons of salt and 50 mL of water. Solution Z contains 6 spoons of salt and 150 mL of water. Which solution is the more dense? Solution Y
A mass piece is placed in each of two cups marked A and B. The mass piece sinks in cup A. The mass piece floats in cup B. Is the mass piece more dense or less dense than liquid A? More Dense
A mass piece is placed in each of two cups marked A and B. The mass piece sinks in cup A. The mass piece floats in cup B. Is the mass piece more dense or less dense than liquid B? Less Dense
A mass piece is placed in each of two cups marked A and B. The mass piece sinks in cup A. The mass piece floats in cup B. Is liquid A more dense or less dense than liquid B? Liquid A is less dense
A mass piece is placed in each of two cups marked A and B. The mass piece sinks in cup A. The mass piece floats in cup B. Will Liquid A float on Liquid B, or will Liquid B float on Liquid A? Liquid A will float on Liquid B because the more dense liquid will always sink to the bottom and the less dense liquid will always float on the top
Which mixture from making and separating mixtures and solutions, were you able to separate with a filter? Only the powder and water
How were you able to separate the salt from the mixture? Evaporation
How are a screen and a paper filter similar? How are they different? Both separate materials; but the filter paper has much smaller holes
What happened when the saltwater solution evaporated? Solid salt was left in the dish
Did the salt look the same as it originally did before evaporation? No, it looks like crystals
What does a salt crystal look like under a microscope? It is square with an X from corner to corner
What item were you able to separate using the magnet? Magnetite (a mineral; iron ore)
What method allowed complete separation of the dry mixture of gravel, powder, salt, and magnetite? 1st use the magnet- magnetite; 2nd add water; 3rd -screen to separate the gravel; 4th- filter to separate the powder; 5th evaporate the water leaving salt crystals.
