Question

below what ph value is food considered too acidic for bacterial growth? 14 ph 7 ph 4.5 ph 2 ph

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
