Step 1:I'll solve this problem step by step, focusing on the pH scale and alkalinity.
Step 2:: Understand Alkalinity
Alkalinity is measured by the pH scale, which ranges from 0 to 14. - pH < 7 is acidic - pH = 7 is neutral - pH > 7 is alkaline (basic)
Step 3:: Recall Typical pH Values
- Milk: $$pH \approx 6.5
Let's review the approximate pH values for each substance:
Step 4:: Analyze Alkalinity
The most alkaline substance will have the highest pH value above 7.
Step 5:: Compare pH Values
- Milk: $$6.5$$ (slightly acidic)
- Orange juice: 3.5 (acidic)
Final Answer
Ammonia is the most alkaline substance, with the highest pH of approximately 11.0.
