Unit 5 Flashcards
Solvent
Able to dissolve other substances.
Solute
The minor component (smaller amount) in a solution,dissolved in the solvent.
Solubility
Referring to the ability for a given substance, The salute, to dissolve in a solvent.
Name 3 things I can be increase the rate of solubility
- increase temperature
- smaller particles (crushed tablet compared to the whole tablet)
- stirring the solution
If you have 80 mL of vinegar and you add 20 mL of water. In this solution, The water is identified as what part of solution?
The water would be this silly because it is the smaller amount.
Is the process of dissolving a salute in the Sullivan become a reaction or a physical reaction? Explain why.
Physical change because the parts never chemical combined.
Why is water described as universal solvent?
The unequal sharing of electrons between oxygen and hydrogen.
Why is the water described as a polar substance
- A positive and a negative end.
- Positive charge.
What Most impact whether a substance will dissolve in water?
Polarity (if it is polar it will dissolve,Nonpolar will not dissolve)
What is a pH level?
Is a measure of how acidic and basic a substance is.
Give a character of acid
- acid taste sour
- acid reacts strongly with metals
- PH level zero through six
When you combine an acid and base what happens (examples:anti acids and HCI)
Acids mixed bases neutralize each other
What is a neutral solutions pH
PH of seven
A liquid with a pH of 3.0 is how many times more acidic then one with a pH of 4.0
10 times
What is acid rain
Acid rain is a rain or any form of precipitation that is acidic than possesses elevated levels of hydrogen ions
