Help with Chemical reactions that make water unstable....

[Mohammed Alhayek9]

Directly without any introduction _

I really want some help from chemical engineers

I was just looking for some chemical reactions that can make water unstable

like when we put it in the water the water will move will not be stable or in an equilibrium state

thank you very much

I'm not sure what kind of instability you mean. The question sounds like the polywater science fiction story.

something that makes water vibrate or any other behavior

Dry Ice (solid CO₂)
Baking Powder (any of several, check your grocery store)
Any mixture of a dry acid and a dry alkali (powdered Citric acid and Baking Soda for instance)

Transition from laminar to turbulent flow in a pipe.
Transition from laminar to turbulent flow in flow past a flat plate.
Taylor instability in viscous flow between concentric rotating cylinders.
Rayleigh stability in heat transfer from below a fluid contained between horizontal flat plates.

how about adding an anhydrous salt, for instance copper sulphate with each molecule removing 7 water molecules?

Google search for; Rotating and Oscillating chemical reactions. Here is an example.
