Unit 5 Flashcards
Define solvent
Able to dissolve other substances
Define solute
The minor component smaller amount in a solution dissolved in the solvent
Define solutibility
Referring to the ability for a given substance the solute to dissolve in a solvent
Name 3 things that can increase the rate of solutibility
1 increase temperature
2smaller particles (crushed compared to whole tablet )
3 stirring the solution
If you 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 because it is smaller amount
Is the process of dissolving a solute in a solvent a chemical reaction or a physical reaction ex playing why ?
Physical change because the parts never chemical combine
Why is water described as the universal solvent
The unequal sharing of electrons betwen oxygen and nitrogen
Explaing what happens to solutibility when you increase the temperature
As you increase temperature the solutibility increases
Why is water described as a polar substance
1 a positive end and a negative end
2 positive charge
What most impacts weather a substance will dissolve in water
Polarity
What is a pH level
Is. Measure of how acidic or basic a substance is
Give characteristics of an acid
Acid taste sour
Acids react strongly with metals
PH level 0-6
When you combine an acid and base what happens
Acid mixed with bases neutralize each other
What is a neutral solutions pH
PH of 7
A liquid with a pH of 3.0 is how many times more acidic than one with 4.0
Ten times
