Explanation:
Reducing Flame:
- In a reducing flame, the borax bead is colorless when heated alone.
- When a salt that imparts a red color to the borax bead in a reducing flame is added, the bead turns red due to the reduction of the metal ions present in the salt.
- This red color is characteristic of certain metal ions in a reducing atmosphere.
Oxidizing Flame:
- In an oxidizing flame, the borax bead can exhibit different colors depending on the metal ions present.
- The color of the borax bead in an oxidizing flame can be blue, green, yellow, or violet, depending on the specific metal ion present in the salt being tested.
- However, since the question mentions that the salt imparts a red color to the borax bead in a reducing flame, the bead will likely not show the same red color in an oxidizing flame.
- Among the options provided, blue is the most common color observed for the borax bead in an oxidizing flame.
Therefore, the correct option is Blue for the color of the borax bead in an oxidizing flame.
