- The Kspfor silver(I) phosphate is 1.8 × 10–18. Determine the silver ion concentration in a saturated solution of silver(I) phosphate.The equilibrium constant of the reaction A(aq) + B(aq) --> 2C(aq) + D(aq) is 13492.3. This implies that at equilibrium, the concentration of the products will be (much less than, much more than, exactly equal to, about the same as) the concentration of the reactants."Calcium ions/oxalic acid equilibrium in the kidney" Base on the above statement, give an equilibrium related to that and answer the following questions: What is the K value of the equilibrium if it is available. Base on Le Chatelier's principle, when will that equilibrium will not meet and what negative effects will happen when the equilibrium is not met. Suggest the preventive measures that can be taken to avoid negative effects whem the equilbrium is not met.
- Calculate the new equilibrium constant with this common ion effect, once it's calculated which way will the chemical equilibrium shiftCesium buffer helps in determining easily ionizable elements in ICP-MS and ICP-OES. But how? Cesium is easily ionizable element it produces more electrons in the plasma. In principle it should also suppress the ionization of metal of our interest. In that case Cesium buffers interferes our analysis. I don’t understand why Cesium helps to reduce the ionization of sodium and potassium, not the ionization of metal of our interest. Can you please explain how cesium helps to reduce the ionization of only a specific metal not the metal of interest?Consider the addition of 0.10M sodium chloride and 0.10M ammonia to a 0.10M silver nitrate solution.What is the overall equation and K?
