Therefore, neither ion will affect the acidity of the solution, so KCl is a neutral salt. Strong acids and strong acids are considered strong electrolytes. You can view video lessons to learn Identifying Acids and Bases. AN does not represent the absolute acid concentration of the oil sample. When an acid is added to a base, a chemical reaction called neutralization reaction. We’re being asked if KOH an acid or a base?. 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). NaOH, KOH, Ca(OH)2 and Mg(OH)2 are examples of strong bases, although the latter two have limited solubility in water. The conj bases of one of the strong acids are so weak they will not behave as bases to make the solution basic. Start studying Eimers - Acid, Base, or Neither?
