(c)AgNO3(aq) is added? (Ag+ forms AgSCN ppt with SCN–)
(d)NaOH(aq)is added? (Fe3+ forms Fe(OH)3 ppt with OH–)
Expert Solution
Step 1
Le Chatelier's principle:
This principle is used to predict the effect of a change in conditions on chemical equilibrium. This principle states that when any system is at equilibrium and if we change in concentration, temperature, or pressure the system changes to a new equilibrium to cancel the change.
