Consider the following Gibbs energies at 25 °C. (a) Calculate ΔG°rxn for the dissolution of AgCl(s). (b) Calcu?
(a) AgCl(s) ==> Ag+(aq) + Cl-(aq)
ΔG°rxn = sum (ΔG°f products) – sum (ΔG°f reactants) = ((1 mole Ag+(aq))(77.1 kJ/mole) + (1 mole Cl-(aq))(-131.2 kJ/mole)) – (1 mole AgCl(s)(-109.8 kJ/mole) = +55.7 kJ/mole
(b) The solubulity product constant is Ksp for the reaction in (a).
ΔG° = -RTlnK, or, K = e^(-ΔG°/RT) = e^(-55,700 J)/(8.31 J/mole K)(298 K) = e^-22.5 = 1.7 x 10^-10
(c) and (d) are done just like (a) and (b). You should get values of
ΔG°rxn = +70.0 kJ
Ksp AgBr = 5.3 x 10^-13
Insoluble AgCl(s) precipitates when solutions of AgNO 3 (aq)… | bartleby – AgNO 3 (aq) + NaCl(aq) → AgCl(s) + NaNO 3 (aq) Δ r H ° = ? The temperature of the mixture rises from 21.15 °C to 22.90 °C. Calculate the enthalpy change for the precipitation of AgCl(s), in kJ/mol.(a) at 10°c, 8.9 10−5 g of agcl(s) will dissolve in 100. ml of water. (i) write the equation for the dissociation of agcl(s) in water. (ii) calculate the 3) The solubility product constant ksp for AgCl can be calculated using the following expression, derived from the equilibrium reaction in part 1, AgCl(s)…Add dilute HCL slowly while stirring and answer the following i) What is the colour of the solution?ii) What … has happened to the copper oxide ?iii) Write the balanced chemical equation for the above reaction.
(a) at 10°c, 8.9 105 g of agcl(s) will dissolve in 100. ml… – Brainly.com – Can anybody provide me the equation by which i can calculate the percentage of drug release during dissolution of a solid oral dosage form? First, You have to find out dissolution method and analytical method for the drug. and for calculation you can use the attached file.The dissolution stoichiometry shows a 1:1 relation between the amount of compound dissolved and the amount of AgCl will precipitate if the reaction quotient calculated from the concentrations in the mixture of AgNO3 and NaCl is greater than Ksp. Consider the dissolution of silver iodideCalculate the voltage after the addition of (a) 65.0 and (b) 135.0 mL of AgNO3. Indicator Electrodes, 4. The titration curve for the previous example is reminiscent of a pH The reference electrode at the left of the line diagram is the coiled Ag | AgCl electrode in the combination electrode (see next slide).
28 Calculate the solubility product of AgCl if asaturated… – Brainly.in – Calculate the value of the equilibrium constant for the reaction at this temperature. As Qsp >> Ksp, precipitation of AgCl(s) will occur. The solubility of gases in water decreases with temperature. The dissolution of a gas is entropically disfavoured and only occurs because it is exothermic. Calculate the value of DG° at 298 K.Well, let us first consider the solubility equilibrium that governs the dissolution of silver chloride…. The crystal structure of NaCl is face-centered cubic, and the crystal structure of AgCl is the same. they decrease in the same order as the solubility products: AgCl>AgBr>AgI. This order is predicted by…Thermodynamic calculations allow us to calculate and predict whether a reaction will be spontaneous. In order to understand how we can perform such · Write the salt/ppt equation for each precipitation reaction indicated. AgCl(s) formation is shown as an example. · Calculate DG° for each reaction. o…
