Question

How might the vinegar solution help keep pickles fresh for a long period of a time?

Answer 1

Vinegar could usually be added to pickles because the added acid of the vinegar inhibits any sort of bacteria from entering the substance, and this would help keep them fresh for a longer period of time too.

Answer 2

Vinegar inhibits the growth of microbes by adding acidic pH to the pickle.

Step-by-step explanation:

Growth of microbes spoils the pickle. Irrespective of their ability to grow in a wide range of pH, each microbial species has its optimum pH. Any deviation from optimum pH slows down or prevents the growth of the microbes. Vinegar serves as a preservative for pickles as it lowers down the pH of pickle and makes it extremely acidic. The extremely acidic conditions do not allow the growth and development of microbes. Hence, the pickle is preserved for a longer time.
