below what ph value is food considered too acidic for bacterial growth? 14 ph 7 ph 4.5 ph 2 ph
Answer
Explanation:
Step1: Recall pH range for bacterial growth
Bacteria generally grow well in a pH range close to neutral (pH 7). Acidic conditions are unfavourable. The lower the pH, the more acidic the environment.
Step2: Compare given pH values
Among 14 pH (highly basic), 7 pH (neutral), 4.5 pH (moderately acidic) and 2 pH (highly acidic), 2 pH is the most acidic.
Answer:
2 pH
