On day one of Hector: Rats, you need to cook up some meth while under attack from various forces. This is done by collecting a variety of ingredients from around the house and then interacting in some way with a laboratory setup on the top floor of the house.
What ingredients do I need to use, and in what order do I need to use them in order to cook meth?
In the event I pick multiple ingredients at once, how do I then choose which ingredient to use at the laboratory setup?
Above is an image of the meth lab and where the specific ingredients are placed when cooking. Note that Mu = Muriatic Acid, Cs = Caustic Soda and Hcl = Hydrogen Chloride. (Image source: PAYDAY wiki, "Rats")
In multiplayer, the required ingredient is synchronized across all players, but the dialog from Bain is not.

Bain has a number of lines where he's incorrect, though he will correct himself shortly afterwards and state the right ingredient. He also has a multitude of non-unique correct lines for what ingredient to put in.
Bain is wrong when he says:
After saying one of the wrong lines, he corrects himself, saying the right ingredient:
Bain is right when he says:
Wrong and right periods have a triple sentence structure. Each of the three sentences are randomly combined. The only reliable sentence that will reveal previous statement right or wrong is the last (i.e.: "...I'm 54% sure").
Correction periods have a double sentence structure. Both sentences will always reveal that the immediate information given is correct.
Examples of last sentences on false previous information:

There are 3 different ingredients: caustic soda, muriatic acid and hydrogen chloride. The order of which to use will be provided by Bain (your handler). Note that the information he gives initially can be wrong, so wait until he confirms that he is sure.
Each ingredient is placed on different parts/equipment in the lab, simply hover over different part of the lab to confirm what you are placing, this way you can be holding multiple ingredients and still apply the correct one.
key to success. However it's worth pointing out that you get the same xp for failing than you do for success. Which is why people speedrun Rats.
muriatic acid and hydrogen chloride -- that's hilarious (they're the same thing, the acid just has water).

Since the Lab Rats heist was added in October 2015, Bain's voice lines are now less confusing.
galacticninja's answer is still mostly correct, but Bain's voice lines have changed.
Bain will now tell you to put in a specific ingredient. 5 seconds later, he will say something like "I'm 89% sure", or "I'm 50% sure", or "these websites are iffy". In this case, the first ingredient he says is correct.
However, he may correct himself after these 5 seconds instead. He will say something similar to "Wait a minute, I messed up! It should have been acid!". In this case, the latter ingredient is correct.
