Stripping voltammetry is a highly sensitive electroanalytical technique for the determination of heavy metals. The analysis involves two steps: (1) accumulation step: applying a potential to reduce metal ions to metal and deposit it on an electrode surface (2) stripping step: scanning the potential in the positive direction to oxidize the deposited metal on the electrode surface to ions. The sensitivity of the method can be controlled by the deposition time and other parameters. In a stripping voltammetric measurement of Cd2+, deposition is undertaken at 5.00 × 10-6 A for 2 minutes. Calculate the mass of Cd (unit gram) deposited on the electrode surface (atomic weight of Cd is 112.4). Answer:
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.
