Would Epsom salt table or baking soda make the better desiccant and why?

Baking soda (sodium bicarbonate) is a better desiccant than Epsom salt (magnesium sulfate) because it has a higher affinity for water molecules. This means that it can absorb more water from the air than Epsom salt, making it more effective at preventing moisture buildup and spoilage.

In addition, baking soda is less likely to cake or form clumps than Epsom salt, which makes it easier to handle and use. It is also a less expensive option, making it a more economical choice for use as a desiccant.

Here is a table summarizing the key differences between baking soda and Epsom salt as desiccants:

| Property | Baking Soda | Epsom Salt |

|---|---|---|

| Affinity for water molecules | Higher | Lower |

| Caking or clumping | Less likely | More likely |

| Cost | Less expensive | More expensive |

For these reasons, baking soda is the better choice for use as a desiccant.
