Question

Hbr is mixed with water. which is the best description of what you would expect to find in the solution? 1. h2br+, oh1−, and water molecules 2. h3o +, br1−, and water molecules 3. hbr molecules and water molecules 4. hbr molecules, h3o +, br1−, and water molecules 5. br1−, oh1−, and water molecules 6. br+, oh1−, and water molecules

Answer 1

The correct answer is 2, H3O + Br-1 and water.
Hydrogen bromide is a strong acid, which dissolves totally in water. In solution HBr will be reduced to hydronium ion {H3O} and bromide ion {Br-}.
