Answer:
Catalase has no effect on the pH of solutions.
Explanation:
Catalase has no effect on the pH of solutions when added to these solutions because it has a neutral pH of 7. So when Catalase is added to solutions having pH 3, the pH will remain 3, when Catalase is added to solutions having pH 5, the pH will remain 5, when Catalase is added to solutions having pH 7, the pH will remain 7, when Catalase is added to solutions having pH 9, the pH will remain 9 and when Catalase is added to solutions having pH 11, the pH will remain 11.
