What is the function of alkaline solution in Biuret's test?
Alkaline levels are essential for the solution to change colour. Without alkaline levels, the colour of the solution would not be detectable.
If you add indicator to an alkaline solution what will happen?
It depends on what indicator you use. An alkaline solution will have a pH-value >7. So if you're using BTB, it'll be blue. If you're using Fenolftalein, then it'll be pink.
What is the color of BTB solution after you exhaled into it?
It turns yellow after we exhaled into the btb solution..:)
Why ammonia is added in heavy metals limit test?
ammonia solution is used to make the solution alkaline. In alkaline solution ,metals give colour with hydrogen sulphide.
What colour does phenolphthalein change to when it reacts with and alkaline solution?
Purple/Pink

What color is the bromthymol blue solution before and after you exhaled into it?
The color of the bromthymol blue solution or blue btb is yellow after you exhaled into it..:)
What is the color of BTB solution after you exhaled it?
It turns yellow
How can pH of a solution be tested?
By dissolving the pH solution a colour change will occur in the solution that should be tested.Compairing the colour of solution to the colours marked on of pH chart we can find out if the solution we tested is of alkaline nature or of acidic nature or neutral.Solutions of pH7are neutral solutions.Solutions below pH7 are acidic solutions and those above pH7 are alkaline solutions.
What color is BTB in an acid?
BTB stains hands and clothes. As carbon dioxide is absorbed from the breath into the solution, forming carbonic acid, the solution changes color from green to yellow.
