Thread: What are the properties of the hydrogen halides?

I need to knwo if hydrogen chlodie, hydrogen bromide and hydrogen iodided are readily soluble in water (and is ther a residue of undissolved gasses left-what?)
The reaction of the gases with amonia ad what they form.
The stability of the gases towards heat.

All of these are soluble in water, and the form storng acids in water. They will react with ammonia since thy are acidic and form the ammonium salts, for instance ammonium chloride for HCl. ( NH4Cl). All of them will be heat stable.
