very helpful tysm :). in general solutions turn darker as reactant concentrationis increased, and more colorless as reactant concentration is decreased. equillibrium is disrupted by concentration shifts because they place more stress on the system. to alleviate induced stress on one side of the reaction (for example, a higher fe3+ concentration), the equillibrium moves toward producing more fe(scn)2+, hence darker color as there is a higher concentration. a vice verse example: adding sodium sulfite to decrease the fe3+ concentration moves compels equillibrium to move toward reactants, decreasing amount of fe(scn)2+ hence a lighter color. pls correct if wrong 🙏 from a fellow ap chem student
By increasing the concentration of one of the reactants, which in this case is the Fe or SCN, there are more reactants and thus it will shift to the right. I think about like I'm adding more reactants and therefore more products are able to be produced which causes more FeSCN2+ to be produced making the solution darker.
I needed the first one. My lab group messed up and I was struggling to explain the reaction. They thought it turned some other color and I was trying to explain it in my lab and couldn't. Now that I know the color and can actually finish my lab 🤦

The way you doing these practicals are awesome. So clear and easy to understand. Thank you so much ❤
Thank you very much! You just helped me finish my essay :)
Thank you so much for this video!! It helped me a lot
Thankyou for this interesting video!!
So both KSCN and Iron III were colorless at the beginning?
Iron III (Fe3+) is yellow in color and when mixed with the clear SCN it creates a product that is Orange/Brown. maybe even blood red
No iron III is pale yellow so it's seen as colorless thro the camera prob
what changes happen with heat and ice
Thankyou
What factor Is responsible for the chemical becoming a dark orange color

Is this an exothermic or endothermic?
forward reaction is exo, reverse reaction is endo.
I hope this helps :)

same man
Good
can't even have orange in Ohio 💀
Lmao
Bro what?
