we then titrated both the aqueous and organic layer. for organic layer, we used 0.1M (S2O3)2- for aqueous layer, we used 0.01M (S203)2- find concentration [I]2 (subscript 2) for aqueous and organic layer
Calculate the total volume of gas (at 133 degrees C and 758 mmHg) produced by the complete decomposition of 1.56 kg of ammonium nitrate.
You add an excess of Ca(OH)2 to water maintained at a particular temperature, stir until the solution is saturated, filter, then determine the [OH-] in the solution by titration with acid
The pKa of hydrogen cyanide is 9.21. In a 100mL solution there are 0.30M of hydrogen cyanide and 0.50M sodium cyanide, there is 0.0050 moles of solid sodium cyanide without changing the volume. Find the resulting pH of the solution.
