all hydrogen halides are covalent gases
they are soluble in water because they react with the water to form ions

this reaction takes place because the hydrogen halide donates a proton (H+) to the water (forming H30+), leaving X- behind (X being a halogen)

therefore HX + H2O -> H30+(aq) + X-(aq)

it is acidic because it fulfills the bronstead-lowry definition of an acid - a proton donor - in that it donates the H+ to the H20

hope that helps

Because when they are in solution/water, they from H+ and 0H- ions, and so because water is polar, it attracts ions and bonds are made between the ions and water molecules. Therefore Hydrogen Halides are soluble. They are acidic because the H+ ion accounts for the acidity.

Any questions, feel free to pm me
