|
A mixture where particles can be seen and easily separate by settling or filtration.
|
SUSPENSION
|
|
A neutral solution has this number as its pH.
|
7
|
|
This does not react with other carbonates.
|
A BASE
|
|
Solutes lower the freezing point of water and that makes this happen.
|
MAKING IT HARDER FOR WATER TO FORM CRYSTALS
|
|
A polar solvent will most likely dissolve this.
|
POLAR SOLUTES
|
|
Things that produce hydroxide ions in water. (i.e. sodium hydroxide, potassium hydroxide)
|
BASES
|
|
This is what you would get if you added a small amount of hydrochloric acid to 4 liters of water.
|
DILUTE SOLUTION
|
|
This measures the concentration of hydrogen ions.
|
pH scale
|
|
The reaction between an acid and a base.
|
NEUTRALIZATION
|
|
The place in the body where the pH is the highest.
|
SMALL INTESTINE
|
|
Adding more solute to a dilute solution causes it to become more of this.
|
CONCENTRATED SOLUTION
|
|
This is how acids are described because they dissolve some metals.
|
CORROSIVE
|
|
A substance that turns different colors into an acid or a base.
|
INDICATOR
|
|
This is caused by the release of pollutants into the air and causes damage to stautes, forests, and lakes.
|
ACID RAIN
|
|
The process that breaks down the complex molecules of food into smaller molecules.
|
CHEMICAL DIGESTION
|
|
When a base reacts with an acid, water and THIS form.
|
SALT
|
|
When acids react with carbonate compounds, This forms.
|
CARBON DIOXIDE
|
|
This forms hydrogen ions when it is dissolved in water.
|
ACID
|
|
This is the part of a solution present in the largest amount.
|
SOLVENT
|
|
Solutes do this to the boiling point of a solvent.
|
INCREASE
|
|
You put salt into a jar of water, shook it up, and allowed it to sit for a day. Now there is crystals of table salt at the bottom of the jar, so what can you say about the concentration of this solution?
|
IT IS "SATURATED" BECAUSE THE EXTRA SALT HAS SETTLED TO THE BOTTOM OF THE JAR
|
|
If you had a jar of water and salt where salt crystals had formed at the bottom, what would happen if you heated the jar? What would happen if you cooled the jar?
|
If you heated the jar, more of the salt would dissolve.
If you cooled the jar, more of the salt would settle at the bottom. |
|
What happens to the particles of a solid solute when the solute is dissolved in a solvent?
|
The particles break apart and are surrounded by the particles of the solvent
|
|
Why must the pH values of the mouth, stomach, and small intestine be different?
|
Because enzymes in these organs work the best at different pH values.
|
|
What two ways is adding antifreeze to the water in a car radiator useful?
|
It raises the boiling point and it reduces the freezing point of the water to prevent possible damage.
|
|
In the equation...
NH3 + H2O -> NH4+ +OH- is ammonia(NH3) an acid or a base? Why? |
Ammonia(NH3) is a base because in a water solution(H2O) it produces hydroxide ions (OH-).
|
|
If you do not know the products of a resulting solution, how could you determine whether it contains ions or a dissolved molecular solid?
|
You could test the conductivity of the solution. If the solution contains ions, it will conduct electricity where as molecular solids do not conduct electricity.
|
|
What chemical reaction would happen if acid rain falls on a lake that has basic water(high PH)? What would happen to the lake's pH?
|
Acid rain has a low pH so it will neutralize the water in the lake and a salt will form. This will make the pH of the lake decrease.
|
|
How is a weak acid different from a dilute acid?
|
A weak acid has a small number of H+ ions.
A dilute acid has just a small amount of acid solute. |
|
How are the dissolved particles of a molecular solid such, as sugar, different from the dissolved particles of an ionic solid, such as table salt?
|
Molecular solids are completely surrounded by solvent but they remain neutral.
Ionic solids will split into ions which are positive and negative. |
