When you mix sand and vinegar, the vinegar will dissolve any minerals in the sand, causing it to clump together or form a sludge-like mixture. This is because the acetic acid in the vinegar reacts with the minerals in the sand, breaking down their structure.
If you mix sand in a solution of vinegar and water, the sand will not dissolve in the vinegar and water solution as it doesn't readily react with them. The sand will likely settle at the bottom of the container due to its higher density compared to the liquid solution.
