We're being asked to classify each substance as a strong acid, strong base, weak acid, or weak base.
Weak acids and weak bases are weak electrolytes that don’t completely ionize but instead reach a state of equilibrium.
However, it’s easier to identify strong acids and strong bases than familiarize yourself with all the weak acids (since the common strong acids have rules and are relatively fewer).
Note: Neutral amines are weak bases
Strong acids and strong acids are considered strong electrolytes. They completely dissociate into ions when dissolved in water.
• Strong binary acids – paired with a highly electronegative atom
Strong binary acids are: HCl, HBr, and HI
• Strong oxyacids (or oxoacids) - have 2 or more oxygens than hydrogens
Classify each substance as a strong acid, strong base, weak acid, or weak base.
HBr, HCl, HNO3, HClO4, HNO2, H2CO3, HCOOH, C2H5COOH, C5H5N, LiOH, NaOH, Ca(OH)2, KOH, CH3NH2
