1) CAUS is Chlorine. Then
CAUS + WATR -> ACID
ACID is more heavy then WATR
ACID + METL -> SALT (also you can make a new element called Natrium or Sodium)
Molten SALT is conductive
ACID is conductive
ACID with electric current -> HYGN and CAUS
Also we need dilute acid (ACID + WATR -> ACID with color from pink to pale pink [like GEL and WATR])
The velocity of SMTH (something) and ACID as fast as more concentrate is ACID.
2) LN2 and NICE with heat -> positive pressure (like LOXY)
3) Carbonated water BUBW is H2O and H2CO3 then it must slowly react with METL.

>my small proposition
Your small proposition would likely break every single save that uses ACID
