Defining Acids & Bases
These substances release hydrogen ions (H+) when dissolved.
What are acids?
A solution with a pH of 7 is considered to be.
What is neutral?
If a solution has a pH of 8.2, then it has _____ M of H+.
What is 6.3 x 10^-9 M?
These types of acids/bases completely ionize in water.
What are strong acids/bases?
Acids turn it red, bases turn it blue.
What is litmus paper?
A substance that accepts hydrogen ions (H+) and releases hydroxide ions (OH-), is called.
What is a base?
A pH value less than 7 indicates this type of solution.
What is acidic?
If a solution has a pH of 2.4, then it has _____ M of H+.
What is 4.0 x 10^-3 M?
Give one chemical example of a strong base.
What is NaOH (sodium hydroxide), KOH (potassium hydroxide), CaOH2 (calcium hydroxide)?
Test used for testing strong bases, turns magenta/pink with bases, colorless with acids.
What is phenolphthalein?
The taste of acids is typically described as ______, while bases often taste ______?
what is sour for acids and bitter for bases?
A pH value greater than 7 indicates this type of solution.
What is basic?
If a solution has a pH of 12.7, then it has _____ M of H+.
What is 2.0 x 10^-13 M?
Give one chemical example of a strong acid.
What is HCl (hydrochloric acid), H2SO4 (sulfuric acid), Nitric Acid (HNO3)?
Used to test strong acids, turns red with acids and yellow with bases.
What is methyl-orange?
This is when a base feels slippery because it reacts with the oils on our skin.
What is saponification?
If a solution has a [H+] of 2.2 x 10^-9 M.
What is pH 8.7?
If a solution has a pH of 1.2, then it has _____ M of H+.
What is 6.3 x 10^-2 M?
Weak acids and bases only partially ionize in water, establishing this type of reaction.
What is equilibrium reactions?
Used to test for neutral pH. Turns green for neutral, blue for basic, and yellow for acidic.
What is bromothymol blue?
When bases and acids react together.
Acid + Base ->
What is neutralization?
Acid + Base -> salt + water
If a solution has a [H+] of 5.1 x 10^-2 M.
What is pH 1.3?
The concentration of hydrogen ions [H+] is measured in these units.
What is moles (M)?
HCl(aq) -> H+(aq) + Cl-(aq)
Is showing a strong acid follow this type of equation.
What is dissociation equations?
