Acids/Bases/Salts 2

Quiz Questions

QuestionAnswer
What does an acid produce in solution? An acid produces hydrogen ions in solution, which interact with water molecules to form hydronium ions.
Any substance that forms __________ in a water solution is a base. H3O+=A base is any substance that forms hydroxide ions in water.
What is the difference between a strong acid and a weak acid? In strong acids, nearly all the acid molecules dissociate into ions. In weak acids, a small fraction of the molecules dissolve in water.
The pH of a solution is a measure of the concentration of _________ in the solution. H+=The greater the H+ concentration, the lower the pH and the more acidic the solution.
What property of bases is evident in soap? Slipperiness
What do you get when you add an acid to a base? Water or a Salt
The closer a substance is to 14 the _______the________. The closer a substance is to 14 the stronger the base.
The closer a substance is to 0 the _______the________. The closer a substance is to 0 the stronger the acid.
What substance has a pH of 7? Water or H20
What does it mean for an atom to be stable? For an atom to be stable, the atom needs to have a full outer shell of valence electrons.
What does it mean for an atom to be neutral? For an atom to be neutral, the atom needs to have an equal amount of protons and electrons.
What is an ion? A ion is something that gains or loses electrons.
What two ions are associated with an acid? The two ions associated with an acid are H+ and H30+.
What ion is associated with a base? A ion associated with a base is salt water.
What two substances do you get when you combine an acid with a base? The two substances you will get when mixing an acid with a base are HCL(Hydrochloric Acid) + NaHCO3= NaCL + H20
What do get when you dissolve an acid in water? Hydrogen Ions
What do acids taste like? Sour
All acids are ______= caustic=_______________ All acids are corrosive = caustic= eat away at something
What type of acid is Vinegar ? Acetic Acid
What type of acid is Citrus Fruits? Citric Acid
What type of acid is Stomach Acids? Hydrochloric Acid
What type of acid is Dairy Products? Lactic Acid
What type of acid is fertilizers? Phosphoric Acid and Sulfuric Acid
What makes up proteins? Amino Acids
What type of acid is Caffeine? A Weak Acid
What are some common bases? Sodium Hydroxide (NaOH), Baking Powder, Soaps, Ammonia (NH3), and many Detergents
Bases taste ________. Bases taste bitter.
What is a strong Acid? Hydrochloric Acid (HCL)
When strong acids are added to water, what happens? When added to water, almost all acid molecules dissociate/seperate into ions.
When weak acids are added to water, what happens? When added to water, only a small fraction of acid dissociates/seperates in the water.
When strong bases are added to water, what happens? The ions dissociate/seperate completely into the water.
When weak bases are added to water, what happens? Not all of the base seperates into ions.
What happens as the H+ concentration increases? The pH decreases and the acidity increases.
