Acid Rain Flashcards
Solvent
Referring to the ability for a given substance,the solute,to dissolve in a solvent
Solute
The minor component(smaller amount) in a solution,dissolved in the solvent
Name 3 things that can increase the rate of solubility
Increase temperature
Smaller particles(crushed tablet compared to whole tablet)
Stirring the solution
If you have 80 milliliter a of vinegar and you add 20 milliliter of water. In this solution,the water is identified as what part of the solution?
The water would be the solute because it is the smaller amount
Is the process of dissolving a solute in a solvent a chemical reaction or a physical reaction? Explain.
Physical change because the parts never chemical change
Why is 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 temperature the solubility increases
Why is water described as a polar substance?
A positive end a negative end
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 an acid
Acidic taste sour
Acids react strongly with metals
pH level 0-6
When you combine an acid and a base what happens?
Acids mixed with bases neutralize each other
What is a neutral solutions pH?
7
A liquid with a pH of 3.0 is how many times more acidic than one with a pH of 4.0?
Ten times
What is acid rain?
Acid rain is a rain or any form of precipitation that is unusually acidic,meaning that is posses elevated levels of hydrogen ions (low pH)
