Answer:
Solid metal
Explanation:
The reduced form of metal ions is the metal in elemental state (simple substance). So, if you have a solution with metal ions and they are reduced, you probably will see the deposition of the metal. For example: if you have a solution with sodium ions (Na⁺), and the ions are then reduced, you will see the aparition of a solid phase of metallic sodium (Na(s)), according to the following half-reaction:
Na⁺ + e- → Na(s)
<span>Water molecules form a complex with metal ions (usually a 6-coordinate complex). And the high charge density on a metal ion draws electrons away from the water molecules, making the O-H bonds more polar than normal. This allows the dissociation of the protons, making solutions of most metal ions acidic</span>
Answer:
The minimum energy required to eject an electron from sodium will be bigger.
Explanation:
red light has a higher wavelength, that mean that the energy that emitted is lower in comparison with the violet light.
If the rate of the photons is the same, 10,000 photons per second, that means that the required energy to take an electron need to be bigger to have the same effect.
Hope this info is useful.
