According to the reference, purified water has no taste.
The taste of water often comes from dissolved minerals, salts, and other substances present in it. However, when water is made extremely pure, these elements are removed.
Based on the provided reference:
- Purified water (just H2O) has no taste.
This means that when water is refined to be almost entirely composed of just hydrogen and oxygen molecules (H₂O), the characteristics that typically give water its 'taste' – like the presence of minerals or additives – are absent.
Why Purified Water Tastes "Like Nothing"
Purification processes, such as distillation, reverse osmosis, or deionization, are designed to remove contaminants and dissolved solids from water. The more effectively these processes work, the closer the water gets to being pure H₂O. Since taste is often perceived from the presence of dissolved substances interacting with taste receptors, water that is essentially pure H₂O lacks these substances and therefore lacks a distinct taste.
For comparison, here's a simplified look at what gives other water types taste:
| Water Type | Common Taste Contributors | Taste |
|---|---|---|
| Tap Water | Minerals (calcium, magnesium), Chlorine, Other trace elements | Varies depending on source and treatment |
| Mineral Water | Specific dissolved minerals | Distinct mineral profiles |
| Spring Water | Minerals from source | Varies, often described as fresh |
| Purified Water | Minimal to none | No distinct taste |
While many people are accustomed to the taste of tap or bottled water which contain varying levels of dissolved substances, purified water stands out as the type specifically noted for having no taste due to its composition of "just H2O."
