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

Which of the following is a  strong acid?

a. C6H5CO2H

b. HCN

c. HNO2

d. HNO3

e. H2O

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 (H2C2O4and 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:
