Unit 5 Flashcards
Define solvent
Able to dissolve other substances
Define solute
The minor component (smaller amount) in a solution, displayed in the solvent
Define solubility
Referring to the ability for a given substance the solute to dissolve
Name 3 things that can increase the rate of solubility
Increase temperature
Smaller particles ( crushed tablet compound to whole tablet)
Stirring the solution
If you have 80 milliliters of Vinegar and you add 200 milliliters of water in this solution the water is identified as what part of the solution?
The water would be the solute because it is a smaller amount
Is the process of dissolving solute a chemical reaction or a physical reaction explain why?
Physical change because the parts never chemical combine
Why is the 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 the temperature the solubility increases
Why is water described as a polar substance
A positive ends and a negative end
A positive charge
What most impacts whether a substance will dissolve in water
Polarity ( if it is polar it will dissolve if non polar will not dissolve
What is a ph level
Is a measure of how acidic or basic a substance is
Give characteristics of a acid
Acids taste sour
Acids react strongly with metals
Oh level 0-6
When you combine an acid and base what happens (example antacids and HCI)
Acids mixes with base neutralize each other
What Is a neutral solution ph
Ph of 7
A liquid with a ph of 3.0 is how many times more acidic then one with a ph of 4.0
Ten times
