Question

Need help with this question. Is my part A right? And also need help with part B and C thank you! 2. You are given the equilsbr un syst.em BioC1(s) 21ag) bissuth(111) chloride (eolprless) bismuth (11) onychloride (white) at a point at which the solution is colorless and no BICCl(a) ia observed. a· which way should the equilibrium shift, to the left or to the right, when water is added until a change is observed? What vould be observed? Explain the shift in terms of Le Chatelier's principle react to emove Some a he Hz Some oc he Hro. b Waich way should the equilibrium shift vhen a fev drops of concentrated lci are added to the system produced in part (a)? What vould be observed? Explain the shift in terms of Le Chatelier's principle c. Which vay should the equilibrium shift when a few drops of concentrated NaoH are added to the aysten produced in part (b)? What would be observed? Explain the shift in terms of Le Chatelier's principle. Recall that NaoB reacts with HC1 and thus removes sone of it. en 143

Explanation / Answer

(a) Yes your Part A is correct.

(b) HCl is in the product side, when HCl is added, it will react with BiOCl to produce BiCl3 and H2O. Hence more of the reactant will form and the equilibirium will shift to left.

(c) NaOH is a strong base and when NaOH is added, it will react with HCl and will decrease the HCl concentration. Again NaOH reacts with HCl produces NaCl and H2O. So, H2O concentration will also increase. Both the cases, that is product concentration decreases and reactant concentration increases. Hence the equilibirium will shift to produce more product that is right side.
