We’re being asked to identify which of the solutions is the most acidic.

Strong acids are considered strong electrolytes. They completely dissociate into ions when dissolved in water.

Strong binary acids – paired with a highly electronegative atom

Common strong binary acids are:             HCl, HBr, and HI

Strong oxyacids (or oxoacids) - have 2 or more oxygens than hydrogens

Common strong oxyacids are:                 HNO3, HClO3, HClO4, H2SO4

Exceptions to the rule are:                       Oxalic acid (H2C2O4and Iodic acid (HIO3)

▪ both have 2 more O than H but are weak acids because carbon and iodine have low electronegativity
