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.
