Question

Indicate your predictions beneath the reaction (using one the following symbols →, ←, ↓, ↑ where appropriate) following the application of stress to the equilibrium reactions:

 

On treatment with 6 M NaOH which direction will the equilibrium adjust to minimize the “stress” Shift left (←) or right (→)?

Fe3+ (aq) SCN- (aq) <-> [Fe(SCN)]2+(aq)


What is the function of the vacuum aspirator? Predict the color shift of the indicator as a consequence of the applied “stress”.

Originally greenish-yellow because of 1M of HCL added. 

HCO3-(aq) <-> CO2(g) + OH- (aq)
