FREE Expert Solution

We’re being asked if KOH an acid or a base?. 


Define acids and bases: 

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
