The equilibrium constant for the reaction Agl(s) — Ag+ (aq) +1 (aq) is the solubility product constant, Ksp = 8.3 x 10-17 at 25°C. Calculate AG for the reaction when [Ag+]=1.5 x 10-3 M and [Br] =1.5 x 10-2 M. Is the reaction spontaneous or nonspontaneous at these concentrations? AG = 98 kJ/mol, spontaneous AG = 92 kJ/mol, nonspontaneous AG = -65 kJ/mol, spontaneous AG = 65 kJ/mol, nonspontaneous AG = -92 kJ/mol, spontaneous
An electrochemical cell was designed in order to determine the solubility product constant, Ksp for PbCO3. The cell uses the half reactions shown below to produce the overall dissociation reaction. cathode reaction: anode reaction: overall reaction: PbCO3(s) + 2e — Pb(s) + Coz- (aq) Ph(s) — Pb2+ (aq) + 2 e- PbCO,(s) — Pb2+ (aq) + CO2 (aq) Which equality correctly represents the relationship between the equilibrium constant expression for the overall reaction and the solubility product constant for PbCO,?...

The cell uses the half reactions shown below to produce the overall dissociation reaction. cathode reaction: anode reaction: overall reaction: PbCO2 (s) + 2e → Pb(s) + CO - (aq) Pb(s) + Pb2+ (aq) + 2 e- PbCO3(s) — Pb2+ (aq) + CO2 (aq) Which equality correctly represents the relationship between the equilibrium constant expression for the overall reaction and the solubility product constant...
5. (36 pts total) To determine the molar solubility and solubility product constant of magnesium carbonate, Matt stirred 5 g of MgCO3 powder in 150 mL of 0.0041 M MgCl2 solution for 15 minutes. After waiting an additional 10 minutes, he separated the undissolved solid by filtration and collected the filtrate in a dry Erlenmeyer flask. He determined the concentration of CO2 in the filtrate to be 1.40 x 10M Answer the following questions based on Matt's experimental data. For...
the hardness of water causes the disolved Ca+2 ion form magnesium carbonate, Mg CO3 which is slightly doluble solids. soaking solid magnesium carbonate in water only yeilds small amounts of free calcium ion that can be captured but still solvated using a chelating milecule called Ethylendiamineteraacetic acid or EDTA. the 2 reactions involved: 1- Mg CO3 ➡ Mg^+2 + CO^-2 keq= 6.8×10^-6 2- Mg^+2 + EDTA ^-4 ➡ MgEDTA ^-2 + CO ^-2 keq= 4.90×10^8 these reactions combine to give...
Pre-Lab for Determination of Solubility Product Constant 1. Write the solubility product constant (Ksp) for the following reaction as a function of the concentrations of the products: Ca(103) (s) Ca²+ (aq) + 210,- (aq) 2. Ca(IO3)2 will ionize in water to produce 10, ions. The 10, ions will react with KI. Write the reaction for this reaction. 3. We will be using starch as an indicator. Why? 4. In this experiment, we will first produce Izby mixing calcium iodate with...
