Answer:
When sodium is added to water, the sodium melts to form a ball that moves around on the surface. It fizzes rapidly, and the hydrogen produced may burn with an orange flame before the sodium disappears. Water is a true solution and is not a colloid. It is a true solution since particles completely dissolve in water. Ocean water is the type of mixture called a solution, because the is dissolved in the water.

Cold water reacts vigorously with all alkali metals. Each process releases hydrogen gas, resulting in the formation of metal hydroxide. As you progress through the group, the reaction's speed and ferocity increase.
- When an excess of NaCl is introduced, negatively charged chloride ions coagulate the positively charged solution of hydrated ferric oxide.
- When sodium is combined with water, it melts and forms a sphere that floats on top. It fizzes quickly, and the hydrogen that forms may burn orange before the sodium disappears.
