The opposite of acidic water is alkaline water.
Alkaline water refers to water that has a higher pH level than regular drinking water. On the pH scale, which ranges from 0 to 14, a pH of 7 is considered neutral. Anything below 7 is acidic, and anything above 7 is alkaline (or basic).
Understanding the pH Scale
The pH scale is a measure of how acidic or basic water is. It's a critical indicator of water quality and its chemical properties.
- Acidic Water (pH < 7): Contains a higher concentration of hydrogen ions (H+). Examples include lemon juice, vinegar, and coffee.
- Neutral Water (pH = 7): A balanced concentration of hydrogen and hydroxide ions (OH-). Pure water is typically neutral.
- Alkaline Water (pH > 7): Contains a higher concentration of hydroxide ions (OH-). Examples include baking soda solution and seawater.

What is Alkaline Water?
Alkaline water is characterized by its higher pH level, typically ranging between 8 and 9. It is slightly less acidic than regular drinking water and contains alkaline minerals such as calcium, magnesium, and potassium. These minerals contribute to its higher pH.
Some proponents suggest that consuming alkaline water can offer various health benefits. For example, some say it can help regulate your pH level, slow the aging process, and prevent chronic diseases like cancer. While these claims are subjects of ongoing scientific research and discussion, the presence of beneficial minerals is well-established.
How is Alkaline Water Produced?
Alkaline water can be found naturally or created through various processes:
- Naturally Alkaline Water: Water that flows over rocks, like springs, picks up minerals, which naturally increase its pH level.
- Ionized Alkaline Water: Created through a process called electrolysis, which separates water into acidic and alkaline streams.
- Alkaline Water Filters: Filters can add alkaline minerals to regular tap water, raising its pH.
- Adding pH-Raising Agents: Substances like baking soda or lemon (which, despite being acidic outside the body, can have an alkalizing effect after digestion) can be added to water to increase its alkalinity.
Key Differences: Acidic vs. Alkaline Water
Understanding the contrast between acidic and alkaline water is crucial, especially when considering its potential uses and effects.
Feature | Acidic Water (e.g., pH 4-6) | Alkaline Water (e.g., pH 8-9) | Neutral Water (pH 7) |
---|---|---|---|
pH Level | Below 7 | Above 7 | Exactly 7 |
Taste | Can be tart or metallic (e.g., distilled water) | Often described as smoother or softer | Typically tasteless |
Mineral Content | Varies, can be low in beneficial minerals | Often rich in alkaline minerals (Ca, Mg, K) | Varies based on source |
Common Uses | Cleaning (vinegar), industrial processes, coffee | Drinking, cooking, some health and wellness uses | Standard drinking water, general use |
Example | Rainwater, Lemon juice, some tap water | Spring water, ionized water | Pure distilled water, most tap water |
Practical Insights and Solutions
While research on the health benefits of alkaline water is ongoing, some individuals choose to incorporate it into their daily routine for various reasons.
- Staying Hydrated: Like any water, alkaline water helps maintain hydration, which is essential for all bodily functions.
- Mineral Intake: Naturally alkaline water can contribute to your daily intake of essential minerals like calcium and magnesium.
- Dietary Balance: Some people use alkaline water as part of a broader dietary approach aimed at balancing the body's pH.
