what is the composition of universal indicator solution?

Here's one source that has a "universal indicator (pH 2-10)".  It may not be the only one:\n\nBromothymol Blue 0.08%\nMethanol (solvent)\nMethyl Red Hydrochloride 0.04%\nPhenolphthalein 0.02%\nThymol Blue  0.1%

Usually it's poly-ethylene glycol.  It's just a big organic molecule that has some polarity.  It also ususually a coloring agent in it.  There are various brands that add other things, but this is the basic composition.

SUN's got it right. Iodine is for starch, and biuret is for proteins (or polypeptides that have at least two peptide bonds).\nWhen these indicators react, we can us a spectrophotometer to quantitate how much of whatever substance you're testing for is present.

more soluble in what solution?

Alright, there are two reasons \n\n1) when you add too much indicator to a titration, you are diluting the solution. Its just like if you were to add twenty drops of water to the solution, you would be changing the concentration. Changing the concentration means the titration might react differently, take much longer to complete, and the product will have a higher mass than what you would expect.\n\n2) SOME BUT NOT ALL indicators react with their solution. Phenolphthalein is an example of a chemical that does not react, (don't ask me to go over the indicators that do react, eg: adding an acid to a base shows you have a base...). If your indicator does react with your solution, then the titration will be less successful. This reason really depends what your indicator is. Bromothymol Blue is an example of an indicator that reactis with acid.

Conveniently measured by Inductively coupled Plasma. Can also get other important boiler species like Al, Na, Ca,Mg,S etc

There's quite a few. Just google solubility chart. Here's one I found.

Since phenol is a (very) weak acid, it might be possible to make a quantitative measurement by titration of phenol solution with a standard solution of alkali using phenolphthalein indicator.\nAnother possibility is to make use of the fact that phenol reacts readily with bromine to form tribromophenol. This would involve a rather complicated process:\n1. Add the phenol to a measured excess of bromine solution;\n2. Then add the solution with the excess bromine to potassium iodide solution (making sure that there is more than enough KI); this produces an equal amount of iodine to the excess bromine.\n3. Titrate the iodine with standard sodium thiosulphate solution (starch indicator).

use the equation  pH= -lgKa+ lg( salt/acid)\n(this equation only applies for buffer system)

When the two solutions are mixed, you'll get a bright yellow precipitant.\n\nPb(NO3)2 + 2 NaI ---> PbI2 + 2 NaNO3
