As the concentration of KCl increases , reaction moves in such a way so as to decrease the concentration of KCl. Reaction moves in backward direction and concentration of products will decrease.
Since the product contains a red colored complex ,as the concentration of products decrease the solution will become less red.
Answer -- turn the solution less red

Hi there Im having trouble with the last question on my lab report sheet. Would both equations be considered correct because they share the common ion effect? Please explain; thank you in advance!! Section E: Thiocyano-iron III Complex Ion: Fe + SCN = FeSCN2+ Yellow red Stress to system Observation Shift CIE or Chem Rx Add 0.2M Fe(NO3)3 Solution fums right Fe3+ + 3NO₂ darker red CIE Add 0.1M KSCN solution turns K + SON darker red right CIE Add...
HW 14 <Question 24 (of 29) 0.68 points 10 attempts left Check my work Enter your answer in the provided box. In a dilute nitric acid solution, Fe' reacts with thiocyanate ion (SCN) to form a dark red complex: [Fe(H2O)6]3t + SCN-→ H2O + [Fe(H2O)sNCS] 2+ The equilibrium concentration of [Fe(H,oNCSmay be determined by how dark the colored solution is (measured by a spectrometer). In one such experiment, 1.0 mL of 0.20 M Fe(NO)s was mixed with L.0 mL of...

My question is #2 for the reaction Fe3+ (aq) + SCN- (aq) FeSCN2+ (aq). The goal is to predict the color change (darker or lighter) for test tubes 2-8. I have attached the supplemental sheets given to help with the problem. The test tubes 2-8 are being manipulated either by temperature or things being added which can be seen by one of the pictures. 2. For reaction "UCTIONS are increased by the same amount. Fe3+ (aq) + SCN (aq) $...
Standard solutions of [Fe(SCN)2-] were prepared and their absorbance measured in order to study the Keq for the reaction Fe3+ + SCN- <=> FeNCS2+ A plot of absorbance verses concentration of [Fe(SCN)2-] is shown below. To determine the Keq for the above reaction, 10.00 mL of 0.00200 M Fe(NO3)3 solution is mixed with 5.00 mL of 0.0020 M KSCN and diluted with 5.0 mL 0f 0.10 M HNO3. The absorbance of this red solution is found to be 0.322....
