- A student prepared two solutions: 1 @ (water + cabbage extract) and 1 @ (buffet + cabbage extract). The student adjusted the solutions to pH = 7 but forgot to label each of them so both were indistinguishable. The student decided to test one of the two solutions and split the solution into two beakers: Sol1 and Sol2. The student was really struggling that day and forgot to label the HCL and the NaOH solutions. Continuing with the experiment, the student added SolA into Sol1 and the color turned light red. What is the identity of SolA? What will the color of Sol2 be after SolB is added? What must the initial solution contain?Which of the following compounds will be the MOST soluble in pure water at 25 ˚C? A. Lead (II) carbonate, PbCO3 Ksp = 7.4×10–14 B. Cobalt (II) carbonate, CoCO3 Ksp = 1.4×10–13 C. Manganese (II) carbonate, MnCO3 Ksp = 1.8×10–11 D. Cadmium carbonate, CdCO3 Ksp = 5.2×10–12 E. Barium carbonate, BaCO3 Ksp = 5.1×10–9I am interested in calculating the carbon system. I know that two of the four CO2 properties (ΣCO2, PCO2, pH,and carbonate alkalinity) can be used to determine the entire CO2 system, but I dont know the equations that can be used to relate a set of properties to the whole system. How can I use pH and ΣCO2 to calculate PCO2 and carbonate alkalinity? Or ΣCO2 and carbonate alkalinity to calculate the speciation of each carbon species?

MM PbCr2O7 = 423.188 g/molThe following reaction is the basis for automatized breath tests for the detection of alcohol(e.g. the Breathalyzer):C2H6O + Cr2O72- --> C2H4O2 + Cr3+ The Cr2O72- ions generate a reddish orange aqueous solution that changes to green as Cr3+ ions are produced due to the reaction with ethanol (C2H6O). If the concentration of the dichromate (Cr2O72-) solution is 0.5 M, theconcentration of Cr3+ is 0.1 M, the concentration of ethanol in the solution is1x10-4 M and the concentration of acetic acid (C2H4O2) is 1×10-4 M calculate the value of Ecell for this reaction at 298 K. The value of E0cell is 1.27 V.
