What will you observe when a mixture of iodine and salt is heated in a...
When a mixture of iodine and salt is heated in a china dish, the following observations can be made:
No change in the china dish is observed:
- This option is incorrect because heating the mixture will cause a reaction between iodine and salt, leading to a change in the china dish.
Salt is left behind in the china dish:
- This option is correct because when the mixture is heated, the iodine will sublimate, which means it will change from a solid directly into a gas without going through the liquid phase.
- On the other hand, the salt (sodium chloride) is stable at high temperatures and will remain in the china dish as a solid.
Iodine is left behind in the china dish:
- This option is incorrect because iodine will sublimate when heated, as mentioned above, and will not be left behind in the china dish.
The mixture starts melting:
- This option is incorrect because iodine does not melt when heated, but rather sublimes.
- Salt does not melt either at the temperatures typically used for heating in a china dish.
In summary, when a mixture of iodine and salt is heated in a china dish, the iodine will sublimate and escape as a gas, while the salt will remain behind as a solid. This is why the correct observation is that salt is left behind in the china dish.
