So when potatoes are immersed in a pH of 2, this would be the acidic side of the pH scale.

Webshowed similar activities. pH also plays a role in enzyme activity. For hydrogen peroxidase, the highest activity was at pH 7. At pH 11, the activity was very low and at pH 1 there was no activity. This is likely because pH affects ionic and hydrogen bonds which are important to enzyme shape and therefore enzyme activity (Reece, et al 2010).
