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 to solve to dissolve in a solvent
Name three things that can increase the rate of solubility
Increase temperature
Smaller particles
Stirring in the solution
If u have 80 millimeters of vinegar and you add 20 millimeters of water. In this solution the water is identified as what part of the solution
The water would be the solute be it is smaller amount
In the process of dissolving a solute in a solvent chemical reaction or a physical reaction? Explain why
Physical change because the part never chemical combine
Why is water described as the universal solvent?
The unequal sharing of electrons between oxygen hydrogen
Explain what happens to solubility when you increase the temperature
As you increase temperature the solubility increases
Why is water described as polar substance?
A positive end and a negative end positive charge
What most impacts whether a substance will dissolve in water
Polarity (polar will dissolve)
What is a ph level?
A measure of how acidic or basic a substance is
Give characteristics of an acid
A measure of how acidic basic a substance is
When you combine and acid and base what happens
Acids mix well with bases neutralize each other
What is a neutral solutions of ph?
Ph of 7
A liquid with a ph of 3 is how many times more acidic than one with ph of 4?
Ten time
