Unit5 Flashcards
Define solvent
Able to dissolve other substances
Define solute
The minor component(smaller amount in a solution dissolved in the solvent
Define solubility
Referring to the ability for a given substance, the solute to dissolve into solvent
3 things that can increase the rate of solubility?
Increase temperature
Smallest particles
Stirring the solution
If you have 80ml of vinegar and you add 20ml of water in this solution, the water is identified as what part of the solution?
Solute
Is the process of dissolving a solute in a solvent a chemical reaction or physical reaction?
Physical change because the parts never chemical combine
Why is water described as the universal solvent?
The unequal sharing of electrons between oxygen and hydrogen
What happens to solubility when you increase the temperature?
You increase the temperature the solubility increases
Why is water described as a polar substance
A positive end and a negative end positive charge
What most impacts whether a substance will dissolve in water?
Polarity (if is is polar it will dissolve, if non polar will not dissolve
What is a ph level
Measure of how acidic or basic a substance is
Characteristics of an acid
Acids taste sour
Acids react strongly with metals ph level of 0-6
When you combine an acid and base what happens
Acids mixed with bases neutralize each other
What is a neutral solution of ph
Ph of 7
A liquid with a ph of 3.0 is how many time more acidic than one with a ph of 4.0
Ten times
