Which of the following is the correct chemical formula for hydrobromic acid?
A
HBr
B
HBrO_3
C
H_2Br
D
HBrO
Verified step by step guidance1
Understand that hydrobromic acid is a binary acid composed of hydrogen and bromine without oxygen atoms.
Recall that binary acids have the general formula HX, where H is hydrogen and X is a halogen element like bromine.
Identify the correct formula by recognizing that HBr represents hydrogen bromide in aqueous solution, which is hydrobromic acid.
Eliminate options containing oxygen atoms (HBrO_3 and HBrO) because hydrobromic acid does not contain oxygen.
Confirm that H_2Br is not a valid formula because bromine typically forms one bond with hydrogen in acids, so the correct formula is HBr.
