You add it to the water sample a drop at a time until the color changes, and the number of drops it took is the reading. That makes the accuracy of the result entirely dependent on the condition of the solution, which is why reagents are treated as a consumable rather than a permanent part of the kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eUse the right number\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eEach numbered solution in a test kit does one job, and they are not interchangeable.
