Question

ph between 7-14
names of enzymes
sucrose
base (alkaline)
optimal ph

Explanation:

To determine which option correctly relates to "pH between 7 - 14", we analyze each:

• "Names of Enzymes": Enzymes have various optimal pHs, not directly about pH 7 - 14 definition.
• "Sucrose": A sugar, unrelated to pH scale classification.
• "Base (alkaline)": By definition, substances with pH between 7 (neutral) and 14 are alkaline (bases). This matches the pH range.
• "Optimal pH": Refers to the best pH for a process (e.g., enzyme activity), not the definition of pH 7 - 14.

The pH scale ranges from 0 - 14. A pH between 7 - 14 is defined as alkaline (basic). "Names of Enzymes" and "Optimal pH" relate to enzyme function, not pH classification. "Sucrose" is a sugar, irrelevant to pH. Only "Base (alkaline)" matches the pH 7 - 14 category.

Answer:

Base (alkaline)
