1. Tables in experience 1:
A.
Test tube 0.5M HNO3 (mL) Drops of Potassium thiocyanate Drops of Ferric nitrate Observation (color)
A 0.5 mL 1 1 Light orange
B 0.5 mL 1 9 Vibrant orange( medium)
C 0.5 mL 5 5 Vibrant red
D 0.5 mL 9 1 Dark shade of orange
E 0.5 mL 9 9 Dark red
B. Removing Fe3+
Test tube 0.5M HNO3
(mL) Drops of Potassium thiocyanate Drops of Ferric nitrate 1% NaOH (mL) Observation
F 0.5 mL 5 5 - The color has changed to vibrant orange
G - 5 5 0.5mL The color has changed to light yellow
Tables in experiment 2 “effects of temperature on a CO2+
0.3 g of CoCl2.6H2O (bright pink color) added to 20 mL of 95% ethanol, the observation was change in color, the color …show more content…
B (Hot water) 3 mL - The color has changed to very dark blue. Whereas A is light purple, D is light blue/light purple, E (cold) light pink, E (Hot) is dark blue.
C (ice water) 3 mL - The color changed from dark blue to light purple.
D 3 mL 5 Light blue/ light purple color
Test tube 3 drops of DI water 6 drops of DI …show more content…
For example, test tube A has the lightest orange color whereas test tube E has the darkest color (dark red), from the results in the first table we can conclude that the more drops of Potassium thiocyanate a test tube has the darkest the color we get and the more drops of ferric nitrate the lighter the color of the solution became, for example test tube B and D, B has 9 drops of Ferric nitrate and 1 drop of Potassium thiocyanate and the color came out was vibrant orange whereas test tube D has 9 drops of Potassium thiocyanate and 1 drop of Ferric nitrate and the color was dark orange. Therefore Potassium thiocyanate has the ability to transfer the equilibrium from product or reactant better than Ferric nitrate.
3. The solution in test tube G has reacted with NaOH and therefore had made product of Fe(OH)3 and the color changed from orange to light yellow which means that the product has less concentration than the reactant, in contrast test tube F solution had reacted with HNO3 and the color had changed from orange to vibrant slightly dark orange, therefore the product(FeNCS) is more than the reactant that will result in shifting the equilibrium from product to
