Solution: Which of the following is a strong acid?a. C6H5CO2Hb. HCNc. HNO2d. HNO3e. H2O
Solution: Which of the following is a strong acid?a. C6H5CO2Hb. HCNc. HNO2d. HNO3e. H2O
Problem
Solution
We’re being asked to identify which among the given acids is a strong acid.
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
Analyzing each of the given acids:
