Question
CrO42-(aq) + 2H+ (aq) 2 CrO72- (aq) + H2O(l) Observations (yellow) on left side (orange) on right
Which of the species in the above equation does the NaOH react with.
Write the NIE for the reaction of NaOH and that species. W hat is name of that type of reaction?
Since that species is reacting with the NaOH, it is being removed from the chromate/dichromate equilibrium.
Which direction will the equilibrium shift when it is removed?
Explain: Are the reactions converting chromate and dichromate reversible? Explain how you know in a complete sentence.
Explanation / Answer
1) H+ will react with NaOH
2) net ionic equation :
H+ (aq) + OH- (aq) ----------------> H2O (l)
this is neutralisation reaction
3) equilibrium shifts to backward direction.
dichromate converts to chromate .
according to lechatliers principle on removal of any one of the reactant the reaction will shift towards backward direction .
