Question

Based on Le Chatalier's Principle, and Studing of how stressingsecond equilibrium can affect an equilibrium, using the followingequilibrium systems Ba+2 + CrO-2 BaCrO4 2CrO-2 + 2H+ Cr2O7-2 + H2O Color of BaCrCl4 percipiate is lightyellow/white When Ba(NO3)2 was added, the percipitate wasformed yellow solid with white percipitate. The solid was dissolvedafter adding the base again, then it turned yellow again a) explain what happend when acid is added. b) explain what happened when base is added Ba+2 + CrO-2 BaCrO4 2CrO-2 + 2H+ Cr2O7-2 + H2O Color of BaCrCl4 percipiate is lightyellow/white When Ba(NO3)2 was added, the percipitate wasformed yellow solid with white percipitate. The solid was dissolvedafter adding the base again, then it turned yellow again a) explain what happend when acid is added. b) explain what happened when base is added Ba+2 + CrO-2 BaCrO4 2CrO-2 + 2H+ Cr2O7-2 + H2O Color of BaCrCl4 percipiate is lightyellow/white When Ba(NO3)2 was added, the percipitate wasformed yellow solid with white percipitate.
