Physical properties of any compound, such as colour, taste, odor depend on PH

PH depends on [H] and [OH] ions concentration

and because of water has equal amount of both H and OH ions so it is colorless and tasteless

Dear Prof. Salam Jassim Hmood

I am surprised that being a business specialist you are asking so good questions in physics. The answers requires some space to delve deeper into physical peculiarities of water molecules and their collective behavior:

Actually, I disagree. Water has scents and tastes, that are due to its sources.

For instance, (clean) rainwater has a very light pleasant smell. Tap water smells, unfortunately, rather chemical (especially chlorine and ammonia). And I also noticed that hard water tastes a vague bit chalky. The only water that has a chance of being tasteless, I assume, is distilled water; but this is only if it were kept free from being stored in something like plastic jugs, etc.

As for its color, this requires a large depth of it in order to be visual to us humans. We will see the water appear blue-green once it is deep enough (assuming that it is free from much particulate matter). I always assumed that it was just the phytoplankton making those colors, but my chemistry professor said that the color of deep water *is* blue (because of the light-waves that are absorbed by the chemicals oxygen and hydrogen; or perhaps reflected).

I think it should not be too surprising that some elements or compounds may have no taste, smell, color, or even feel. All it really means is that some of our sensors, such as those related to smell, taste, and vision, are not designed to operate in regions where water might be detectable. Some other of our sensors do detect the presence of water, however. When we touch it, it's detectable.

So here's an example. Our eyes operate within the EM spectrum, roughly in a range between 430 and 770 THz (terahertz). We call that light. And light going through (pure, clear) water does not change color. But, if you go down in frequency, to the RF region, say in the MHz and GHz regions, water very much affects EM radiation. It's just that our eyes don't operate in that region.

Now let's consider that our eyes did operate at those lower frequencies. In that case, water would appear opaque and colored. EM radiation travels better through water in the 3-30 kHz range than it does at 100 MHz. So, water would operate just like a colored filter, when light shines through it.

And why stop at water? We also can't see or smell O2, CO2, and CO, for example, yet we can see and smell many other gases, with no problem at all. Like SO2, rotten eggs.

Short answer: it's how our sensors are designed, that makes water appear clear and odor-free. To a different sensor design, it would not appear that way.

(Julia, what you are describing is the taste or smell of impurities in the water, not the smell or taste of H2O. Mix in minerals or what have you, and everything changes. Even color, at high enough concentration of the impurities.)

All compounds have certain physico-chemical properties. Water has the said properties. So water is like that only. But, certainly it varies with source, salt concentration, mixture if other tiny particles, etc. Water is regarded as a unique liquid compound, very much related to the existence of all lives in our good earth, and, therefore, regarded as precious.

Following

Water has both H+ and OH- ions in equal concentration. Compounds having H+ ions are sour in taste and those having OH- are bitter but water has both the ions in equal concentration so it is tasteless. Pure water is colourless because it has no minerals and trace elements. Also. it can be said that water doesnot absorb any colour. The human eye can precieve electromagnetic waves having wavelength in between 400 to 700 nano meter. As a result, pure water seems to be colourless.

Thanks dear colleagues for sharing your vlaued thoughts

Thanks dear colleagues for sharing your vlaued thoughts

I think the most healthy water has no taste, no color and no smell as it is the origin of life on our planet earth.

It is enough that only water gives us sense fill after drink ”irrigate after thirst”

If Water is colorless,Odorless and tasteless hence it is answer-less also

because it using in any food processing as a solution

Physical properties of any compound, such as colour, taste, odor depend on PH

PH depends on [H] and [OH] ions concentration

and because of water has equal amount of both H and OH ions so it is colorless and tasteless

Interesting answers

Thanks

God, nature made it like that.

Water is tasteless because we don't have any taste receptors for water which makes sense as our taste buds are immersed in saliva which is mostly water.Water is odorless because our olfactory receptors are wet with mucus that is mostly water, too

Interesting answers Thanks dear colleagues for sharing your thoughts

Water is colorless when it is small, but it takes a blue color when the depth of the layers increases. This is a property in the origin and essence of the water, due to selective absorption in the red field of the visible spectrum and scattering of white light. Water vapor is essentially a colorless gas

And the water was a taste for all the food from vegetables and fruits with one taste, which is the taste of water, so how to eat it

If the water had a smell, then all the foods would have a single smell, so how can they eat it after that? But the wisdom of God in creation required that the water that we drink and coordinate the animal and plant fresh water, without any color, taste or smell .
