Consider the following data on some weak acids and weak bases: formula hydrocyanic acid HCN acid name hydrofluoric acid solution 0,1 M KCN 0.1 M HONH3Br 0.1 M NaCl HF 0.1 M C₂H5NHCI Ka 4.9 x 10 6.8 x 10 -10 Use this data to rank the following solutions in order of increasing pH. In other words, select a '1' next to the solution that will have the lowest pH, a '2' next to the solution that will have the next lowest pH, and so on. pH -4 ✓ choose one 1 (lowest) 2 3 4 (highest) 3 base choose one Ⓒ Kb formula pyridine CH₂N 1.7 × 10 hydroxylamine HONH₂ 1.1 × 108 name -9
Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
