Question

1. Describe how you could show that hydrogen halides are very soluble in water.

2. How does the pH change when hydrogen halides dissolves in water? Name the solutions that form.

3. Why is sodium chloride used on roads in winter?​

Answer 1

Answer:

1. Hydrogen halides are diatomic inorganic compounds with the formula HX where X is one of the halogens: fluorine, chlorine, bromine, iodine, or astatine.[1] Hydrogen halides are gases that dissolve in water to give acids[citation needed] which are commonly known as hydrohalic acids.

2. Upon dissolution in water, which is highly exothermic, the hydrogen halides give the corresponding acids. ... With the exception of hydrofluoric acid, the hydrogen halides are strong acids, with acid strength increasing down the group.

3. Ice forms when the­ temperature of water reaches 32 degrees Fahrenheit (0 degrees Celsius), and that includes ice on roadways. Road salt works by lowering the freezing point of water via a process called freezing point depression. The freezing point of the water is lowered once the salt is added, so it the salt makes it more difficult for water to freeze. A 10-percent salt solution freezes at 20 degrees Fahrenheit (-6 Celsius), and a 20-percent solution freezes at 2 degrees Fahrenheit (-16 Celsius).
