Hi there, new person, welcome to the Chemical Forums. You've already been directed to read the forum rules, and I hope you get a chance to do so shortly. An important part of the rules is, that our forum isn't a place where people dump complete answers to any old question. We try to help people learn to help themselves. So lets begin to work together on that ...
You question isn't one that's easy to answer, and I'm going to start by giving you some hints:
1). I've moved your question to the Analytical Chemistry sub-forum. When you want to know What? and How much? for an unknown sample, the type of chemistry you want is called analytical chemistry. High school chem labs aren't were I want to go when I want those sorts of questions answered.
2). You didn't really ask the question the way a chemist would ask it. Maybe you're new, or maybe we're facing a language barrier. Not a real problem, but you don't want to "indicate" these reagents, you want to "qualify" and "quantify" them. It just leaves me wondering, are you ready for the answer if you don't understand the terms?
3). Detecting these compounds won't be easy, or simple.
4). Determining how much is often a separate problem from identity. You also don't ask for how much the final amount is. You instead ask in "recipe" amounts, which is a funny way to ask for analytical results. As though you have a recipe, and you want to know is been followed. But think about it -- 1 mg, per liter? per 100 g? per 1000 metric tons?, in a 10 mg sample? In a 4 mg sample? If I told you it was certainly impossible to have so many mg of unknown in a 3 mg sample, you'd just say "Duh, that's less than the sum" Fine, but what do you mean?
