Quiz Questions
Question | Answer |
---|---|
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. |
