I still can't believe that Epsom Salt is mostly water

TL;DR

Epsom salt contains a significant amount of water, and the process of extracting it is explored in this video.

Transcript

this video has been sponsored by audible for a long time now i've been kind of fascinated by bath salts maybe surprisingly though i'm not talking about the drug that's commonly known as bath salts and i actually just mean the salt that you can get at the pharmacy to make a relaxing bath at least here in montreal the most common one is epsom salt an...

Key Insights

• 💦 Epsom salt contains a significant amount of chemically bound water, making up around 53% of its weight.
• 👻 Heating Epsom salt allows the release and separation of water through distillation.
• 💦 The water content of Epsom salt can be extracted, although the process can be time-consuming and challenging.
• 💦 Epsom salt may have obtained its water from a natural source where it was mined.
• 😑 The water extracted from Epsom salt can be purified using activated charcoal and mixed ion exchange resin.
• 💦 The taste of the extracted water is generally unpleasant, with a sulfur-like smell.
• 💁 Epsom salt sold as the heptahydrate form has practical reasons due to safety concerns and clumping issues.

Questions & Answers

Q: How is the water in Epsom salt chemically bound to the salt crystals?

Epsom salt, chemically known as magnesium sulfate heptahydrate, has seven water molecules bound to it, forming part of its solid crystal structure.

Q: Can the water in Epsom salt be easily separated from the salt?

With heating, the bonds between the water and salt can be broken, allowing the water to be distilled and collected separately.

Q: How much water can be obtained from a large container of Epsom salt?

In theory, a 4 kilo container of Epsom salt contains over 2 liters of pure water, which is almost enough to fill half the container.

Q: What happens when the Epsom salt reaches higher temperatures during the distillation process?

At higher temperatures, the remaining water is released from the Epsom salt, but it becomes more difficult to separate, requiring a longer time and higher temperatures.

Summary & Key Takeaways

• Epsom salt, commonly used for relaxing baths, contains water that is chemically bound to the salt crystals.

• The water content of Epsom salt is around 53% by weight, making it mostly water.

• The video shows an experiment to extract the water from Epsom salt using heat and distillation.
