🤓 Based on our data, we think this question is relevant for Professor Ervin's class at UNR.
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 (H2C2O4) and Iodic acid (HIO3)
▪ both have 2 more O than H but are weak acids because carbon and iodine have low electronegativity
Which of the following solutions is the most acidic?
(a) 0.2 M LiOH
(b) 0.2 M HI
(c) 1.0 M methanol (CH3OH)
