Separation
This would separate iron and sand.
What is a magnet?
The substance that gets dissolved in a solution.
What is a solute?
Vinegar and Baking Soda creates this gas.
What is Carbon Dioxide?
Why does mixing vinegar and baking soda create an irreversible change?
What is, because it turns into carbon dioxide which you cannot reverse a gas reaction.
Sean wasn’t paying attention in the kitchen, and accidentally added cornstarch instead of sugar to the water while he was making lemonade. Is there a way he could get the cornstarch out and still be able to drink his mixture? Is this mistake reversible or irreversible?
What is you can through filtering or decanting. It is a reversible process?
This would separate salt and water.
What is evaporation?
This is what a solute dissolves in.
What is a solvent?
Carbon dioxide is not...?
Give an example of a reversible change.
What is water, and ice?
This would separate mud and gold
What is a sieve?
This is what a solute and solvent turn into when mixed.
What is a solution?
The invisible layer that forms on top of a liquid.
What is surface tension?
Give an example of a solution.
What is salt water?
To pour off the top layer without disturbing the layers below.
What is decanting?
What is a heterogenous mixture.
The force of attraction between particles of a substance.
What is cohesion?
Give an example of a suspension.
What is sand and water?
A mixture in which very small particles of a solid remain without dissolving.
What is a suspension?
A type of homogeneous mixture in which the solute is evenly spread throughout the solvent, usually a transparent liquid.
Homogenous Mixture
If a liquid is tested with red and blue litmus paper and both papers turn red, that means it is...?
What is an acid?
Why does a drop of water stay in a dome shape, while some other liquids flatten out?
What is surface tension from gravity and cohesion from the water molecules?
