Unit 5 Flashcards
Define solvent
Able to dissolve other substances
Define solute
The minor component in a solution, dissolved in the solvent
Define solubility
The ability for a given substance to dissolve in a solvent
Name three things can increase the rate of solubility
Increase temp.
Smaller particles
Stirring the solution
You have 80ml of vinegar and 20ml of water, why would water be the solute
B/c it is the smaller amount
Is dissolving solute in solvent a physical or chemical change
Physical b/c they never chemically combine
Why is water known as the universal solvent
The unequal sharing of electrons between oxygen and hydrogen
What happens to solubility when you increase the temp
As you increase the temp the solubility increases
Why is water a polar substance
A positive end and negative end make a positive charge
What mostly effects whether a substances will dissolve in water
Polarity
What is a ph level
Is the measure of how acidic or basic a substance is
Give characteristics of acids
Taste sour
React strongly with metals
Ph level 0-6
What happens when you combine an acid and a base
Neutralize each other
What is a neutral ph level
Ph7
How many times more acidic is a ph level of 0.3 than ph of 0.4
Ten times
