Unit 5 Flashcards
Define solvent
Able to dissolve other substances
Define solute
The minor component in a solution, dissolved in the solvent
Define solubility
Referring to the ability for a given substance, the solute, to dissolve in a solvent
Name 3 things that can increase the rate of solubility.
- increase temperature
- smaller particles
- stirring the solution
If you have 80 milliliters soft vinegar and you add 20 milliliters of water.
The water would be the solute because it is a smaller amount.
Is the process of dissolving solute in a solvent a chemical reaction or a physical reaction.
Physical change because the parts never chemically combine.
Why is water described as the universal solvent.
The unequal sharing of electrons between oxygen and hydrogen.
Explain what happens to solubility when you increase the temperature
As you increase temperature the solubility increases
Why is water described as a polar substance.
A positive and a negative end positive charge
What most impacts whether a substance will dissolve in water.
Polarity
What is a ph level
A measure of how acidic or basic a substance is.
Give characteristics of an acid.
- sour
- reacts strongly with metals
- ph level 0-6
When you combine an acid and base what happens
Acids mixed with bases
What is a neutral solution ph
Ph of 7
A liquid with a ph of 3 is how many times more acidic than the one with a ph if 4
