11/2/13 Lab 8 PostLab - Eq. and LeChatelier's Principle www.webassign.net/web/Student/Assignment-Responses/view_key?dep=7011484 1/10 Current Score : 24.5 / 25 Due : Friday, November 1 2013 11:00 PM EDT 1. 1/1 points | Previous Answers NCSUGenChem102LabV1 8.POST.01. Green checks and red X's are not displayed for this question. Consider the equilibrium involving the acid-base indicator methyl orange. Indicators are used to provide a visual signal when a solution rapidly changes pH. HC 14 H 14 SO 3 (red) + H 2 O C 14 H 14 SO 3 (yellow) + H 3 O + (a) What color is the indicator in a basic solution? (Basic solutions are prepared by removing H 3 O + ion or by adding OH ion.) (b) Heating the exothermic reaction would cause it to turn red. red.

Green checks and red X's are not displayed for this question. Consider the following equilibrium. Assume that the initial solution is green (mixture of blue and yellow) and predict the color that the solution would turn after each action. [Cu(H 2 O) 4 ] 2+ (blue) + 4 Br [CuBr 4 ] 2− (yellow) + 4 H 2 O (a) Adding AgNO 3 , precipitating AgBr, would cause it to turn blue. blue. (b) Cooling the exothermic reaction would cause it to turn yellow. yellow. Additional Materials Equilibrium and Le Ch telier
