electrochemistry aqueous-solution solubility. Example #1: Calculate the solubility product of AgI at 25.0 °C, given the following data: 1) The chemical equation for AgI dissolving is: Note: some instructors might insist that you round the answer off to two significant figures. Please provide some assistance on understanding how to get the half reactions (balanced) all the way to the solubility for the question below, using the nernst equation and solubility equation. The substances are listed in alphabetical order. Chemistry formula for class 12 chapter- Liquid Solutions. The Ksp is determined directly from the electrochemical data. 43 2 2 silver badges 4 4 bronze badges \$\endgroup\$ add a comment | 3 Answers Active Oldest Votes. Recall that the definition of solubility is the maximum possible concentration of a solute in a solution at a given temperature and pressure. In the calculation of solubility of a sparingly soluble salt. Thus, charge on one g-ion of N 3- = 3 × 1.6 10-1 9 × 6.02 × 10 23 = 2.89 × 10 5 coulomb _____ Example 2. © BrainMass Inc. brainmass.com October 2, 2020, 3:51 am ad1c9bdddf, An Electrochemical Cell and Evaluating Solubility Product Constant, Electrochemical titration of AgNO3 with Nal, Electrochemical cells, Bonds, and Lattice, Understanding Thermodynamics and Electrochemistry, oxalate concentration for calcium oxalate to precipitate. The results show that both DO2 and CO2 decrease as the solution viscosity (η) increases significantly with increasing concentration of NaOH. Once you realize that, you can write the balanced chemical equation for the cell reaction and can calculate E 0 : Zn s → Zn 2+aq + 2e - and E 0ox = +0.76 V. 2Ag +aq + 2e - → 2Ag s and E 0red = +0.80 V. 4. The possibility of studying the gaming table. Please provide some assistance on understanding how to get the half reactions (balanced) all the way to the solubility for the question below, using the nernst equation and solubility equation. Photographic films are based on the sensitivity of AgBr to light. Batteries … So we have the following semireactions: P b X 2 + + 2 e X − P b (cathode) P b P b X 2 + + 2 e X − (anode) And for the anode we also have. share | improve this question | follow | edited Aug 5 '17 at 21:27. andselisk ♦ 31k 10 10 gold badges 96 96 silver badges 180 180 bronze badges. Solution: Charge on one ion of N 3-= 3 × 1.6 × 10-1 9 coulomb . Electrochemistry is the study of chemical processes that cause electrons to move. The solubility products \$(K_{sp})\$ for \$\ce{AgCl}\$ and \$\ce{CuI}\$ are \$\pu{1.8e–10}\$ and \$\pu{1.0e-12}\$, respectively. … E = 0.80 V. This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here! Contents The Relationship Between K sp And the Solubility of a Salt . 2. Note also that you never have to use the K sp expression to calculate anything. Since P b ( N O X 3) X 2 dissociates completely, while P b S is a salt with a low solubility, the left semicell will be the cathode and the right one the anode. 23 1 1 gold badge 1 1 silver badge 3 3 bronze … The part that I really have no clue … Solved Examples on Electrochemistry Example 1. We use Flash technology. Please provide some assistance on understanding how to get the half reactions (balanced) all the way to the solubility for the question below, using the nernst equation and solubility equation. Add Remove. Electrochemistry Electrochemistry is that branch of chemistry which deals with the study of production of electricity from energy released during spontaneous chemical reactions and the use of electrical energy to bring about non-spontaneous chemical transformations. Importance of Electrochemistry 1. How much charge is required to reduce (a) 1 mole of Al 3+ to Al and (b)1 mole of to Mn 2+ ? Merging electrochemistry with thermodynamics gives this formula: \[\Delta G = -n F E_{cell} \] Cell potential is different for each voltaic cell; its value depends upon the concentrations of specific reactants and products as well as temperature of the reaction.
