Answer the following question given this paragraph: Solution The charges, as well as the atoms, must balance in reactions. The silver atom is being oxidized from the 0 oxidation state to the 1+ state. Whenever something loses electrons, something must also gain electrons (be reduced) to balance the equation. Oxygen is a good oxidizing agent for these reactions because it can gain electrons to go from the 0 oxidation state to the 2 state. Q: When something loses electrons, it must also? A:
OPTIONS:
- reduce protons
- slow down
- gain protons
- gain electrons

Answer: gain electrons

Question: Answer the following question given this paragraph: An acid-base indicator is a substance that displays different colors when in the presence of an acid or a base. How does that work? An indicator is a weak acid that ionizes within a known pH range, usually about 2 pH units. We can represent the protonated form of the indicator molecule as HIn and the deprotonated form as In . The following equilibrium exists for the indicator. Q: A substance that displays different colors when in the presence of an acid or a base is called what? A:
OPTIONS:
- pH scale
- reactor
- litmus test
- an acid-base indicator
Answer:
an acid-base indicator
