|
hydrogen ions
|
|
List four properties of acids?
|
sour taste, turns blue litmus paper red, can neutralize bases, and reacts with active metals to form hydrogen gas.
|
|

|
hydroxide ions
|
|
List four properties of bases.
|
slippery feel, turns red litmus blue, bitter taste, reacts with acids to form water and salt.
|
|
What are the products of a neutralization reaction?
|
water and salt
|
|
What is the pH range of acids? of bases? of neutral solutions?
|
pH is less than 7 for acids, pH is greater than 7 for bases, and pH equals 7 for neutral solutions
|
|

|
basic
|
|

|
basic
|
|

|
vinegar
|
|
Which of the following materials could be used to neutralize vinegar? lemon juice, ammonia, HCL, tea, NaOH, or water.
|
ammonia
|
|
Identify these solutions as acidic, basic, or neutral.
pH equals 12, pH equals 2, and pH equals 7. |
basic, acidic, and neutral
|
|
How does surface are affect the rate of solution for MOST substances.
|
When there is an increase in S.A
the solubility rate will go up. When there is a decrease in S.A the solubility rate goes down. |
|
How does temperature affect the rate of solution for MOST substances.
|
When the temp. is increased most substances solubility will increase. When the temp. is decreased most substances solubility will decrease.Except for when gasses are in a liquid. When temperature is increased in this situation soulubility rate will go down. And when temp. decreases solubility rate will go up.
|
|
How does turbidity affect the rate of solution for MOST substance.
|
As turbidity increases solubility increases. As turbidity decreases solubility decreases. Except when gasses are in a liquid. In this situation when turbidity inc. solubility dec. and when turbidity dec. solubility inc.
|
|
Define turbidity.
|
particles suspended in a solution that are the result of stirring and shaking.
|
|
How does relation to saturation point affect the rate of solution for MOST substances.
|
The closer you are to the saturation point the less soluble the substance is. The farther you are from saturation point the substance will be more soluble.
|
|
What are the four characteristics of a true solution?
|
same substance throughout, sugare does not settle, and no visible particles.
|
|
Why are Ca(CO3) and Al(PO1) insoluble in water?
|
Because they are nonpolar
|
|
What is used to help dissolve fat into water?
|
detergents
|
|
What is the general rule about the solubility of solids as temperature increases?
|
As temperature increases solubility of gas decreases.
|
|
what other factors effect the solubility of gases?
|
rate of turbidity.
|
|
Why is salt used to melt ice on sidewalks and driveways?
|
Water from snow and the salt require a much lower temperature to freeze.
|
|
Name two deliquescent substances.
|
calcium chloride and magnesium chloride
|
|
Who proposed that the properties of acids were actually properties of the hydrogen ion?
|
Arrhenius
|
