Question

You freeze a bottle of milk soda in your freezer so it becomes a solid. When you take it out and the solid just just starts to thaw, how does the liquid tastes like? Explain why. What is the concentration of milk in the liquid when it first thaw? How does the sugar concentration change in the solid as it melts continuously and you drink the liquid? Could you obtain pure water from your soda? How? At room temperature (25 degree C), how much sugar can you put into water before you see sugar bits (crystals) form?

Explanation / Answer

Taste of anything depends on several factors like :
- temperature
- ions contained
- conservation additives, like chlorine
- possibly bacterial developpement
- flavor molecules

When freezed the molecules of milk start to expand, the water content in milk increases as it absorbs the molecules present around when freezing.

1. Hence after it thaws it tastes little watery

2. The reason for change is the expansion of liquid accompanied by increase in water content.

3. Concentration of milk will be lesser than what initially was the concentration.
