Universal indicator is an aqueous solution of many indicators: methanol, propan-1-ol, phenolphthalein sodium salt, methyl red and monosodium salts of bromothymol blue and thymolblue. Most of these have a very complicated process associated with it during its manufacture.
Universal indicator is almost always a solution. You add a few drops of it to your solution, shake and look at the colour of the indicator. Generally red means acid, green means neutral and blue means alkaline.
