Water on Venus?

[Ammonia]

I have read some astronomy books and watched a few documentaries about Venus.

They say that Venus has very little water as most of the water molecules have been broken up by UV light and heat out into space.


But Venus has a extremely dense layer of sulphuric acid clouds.

Could all the water in Venus be in these sulphuric acid clouds instead.

If I remember chemistry right.

Sulphur dioxide and or trioxide when mixed with water creates sulfuric acid. This happens on earth with acid rain.

The sulphur in Venus must of originated from a period in its past with high volcanic activity.

I don't know about water being "bonded" in sulphuric acid.
However, I do know from the results of Venus Express that there is a lot of water loss still going on, as shown by Barabash et al.
With the escape rate ratio Q(H+)/Q(O+) = 1.9, this speaks for water loss.

Note: though water vapor is a much smaller percentage of Venus's atmosphere than Earth's, if you take into account its much more massive atmosphere Venus's atmosphere has roughly half as much water as Earth's, which is nothing to sniff at.
