Question
A student prepares an equilibrium solution by mixing 5.00ml 0.00200 m Fe3+ 2.00 ml 0.00200 mSCN- and 3.00 ml 0.1m HNO3 what are the initial concentrations of Fe3+ and SCN- in this solution A student prepares an equilibrium solution by mixing 5.00ml 0.00200 m Fe3+ 2.00 ml 0.00200 mSCN- and 3.00 ml 0.1m HNO3 what are the initial concentrations of Fe3+ and SCN- in this solution A student prepares an equilibrium solution by mixing 5.00ml 0.00200 m Fe3+ 2.00 ml 0.00200 mSCN- and 3.00 ml 0.1m HNO3 what are the initial concentrations of Fe3+ and SCN- in this solutionExplanation / Answer
From the given data,
Initial concentration [Fe3+] = 0.002 M x 5 ml/10 ml
= 0.001 M
Initial concentration [SCN-] = 0.002 M x 2 ml/10 ml
= 0.0004 M
