Does celery stay fresher in hypotonic water or hypertonic water?

Celery stays fresher in hypotonic water because it creates a lower concentration of solutes inside the celery cells compared to the surrounding water, allowing for water to flow into the cells through osmosis and keep the celery crisp. In hypertonic water, the higher concentration of solutes outside the celery cells would cause water to move out of the cells, leading to wilting.

The pickling process creates an acidic environment that is inhospitable to bacteria, slowing down their growth and spoilage of the onions. The addition of vinegar or other acidic ingredients lowers the pH of the solution, inhibiting microbial growth and extending the shelf life of the pickled onions. Additionally, the salt in the pickling solution helps draw out moisture from the onions, further inhibiting bacterial growth.
