Strong and weak acids and bases

“How do different types of acids and bases dissolve in water?”

 

Acids and bases are like two sides of the same coin, the former have too much hydrogen anions, while the former have too much oxalate cations. When some of these substances are poured into water, the acids will ionize (decompose) and the base will disassociate (decompose). However, these compounds do not always dissolve in the same way. Some of them completely dissolve, while some of them will only partially dissolve. When an acid/base fully decomposes, it is called a strong acid. Strong acids and bases produce a lot of electrolytes, which makes the resulting solution especially conductive. The 6 strong acids include Hydrochloric acid [HCl], Hydrobromic acid [Hbr], Hydroiodic acid [HI], Nitrous acid [HNO3], Chloric acid [HClO3], Perchloric acid [HClO4], and Sulfuric acid [H2SO4]. By contrast, acids that only partially dissolve are called weak acids/bases. Since only part of the weak acids and bases decompose, the solutions are not especially conductive. Therefore, the difference between the two types are just about how much they dissolve.
