No, there would be no dangerous reaction if you cut a lemon into four slices, pour salt in the middle, and let it sit. This is a safe and common combination, often used for culinary or household purposes.
Here’s what happens:
Lemon juice (citric acid) is mildly acidic.
Table salt (sodium chloride) is a neutral compound.
When salt is added to lemon slices, the salt may draw out the juice via osmosis and slightly speed up oxidation or fermentation if left for a long time. But:
No toxic gases are produced.
No harmful chemical reactions occur.
It's actually used in preservation, cleaning, or aromatic purposes (e.g., natural air fresheners or pest repellents).
So unless you’re mixing in other unusual or reactive substances, this combination is entirely non-hazardous.
