Which aqueous solution listed below would have a pH = 1.00?
I. 0.10 M HBr (aq)
II. 0.10 M HOBr (aq)
III. 0.10 M NaBr (aq)

HBr is a strong acid, so it completely dissociates in water to form H+ and Br- ions. The concentration of H+ ions in a 0.10 M HBr solution would be 0.10 M, which corresponds to a pH of 1.00. HOBr is a weak acid, so it would have a higher pH than 1.00. NaBr is a salt and does not have any effect on pH.
