Question

When magnesium ribbon is ignited, the flame produced by it is:

• A. Yellow
• B. Blue
• C. Dazzling white
• D. Red

Hint:

Magnesium burns with a dazzling white flame and forms magnesium oxide (\text{MgO}).

Answer 1

The Correct Option is C

Step 1: Understanding the combustion of magnesium. When magnesium ribbon is burned in air, it reacts with oxygen to form magnesium oxide (\text{MgO}). This reaction produces an intense dazzling white flame. \[ 2Mg + O_2 \rightarrow 2MgO \]
Step 2: Explanation of incorrect options.
- Yellow, Blue, and Red flames are characteristic of different substances, but not magnesium.
