Methyl orange indicator provides yellow color in ___.
Methyl orange is one of the commonly used acid-base indicators (the others being phenolphthalein and litmus). Its primary purpose is to indicate a specific pH. In general, indicators are used to indicate the end of a reaction and they do so by changing the color of the solution. Hence, they are also known as color change indicators.
In the case of methyl orange, it provides yellow color in alkaline and neutral pH conditions. It changes its color to orange-yellow at a pH of about 4.4 and then changes color to red at a pH of 3.1.
Methyl orange is commonly used in water quality testing for measuring the amount of acidity or alkalinity in a given water sample. It is also used in the textile industry for dyeing and printing purposes.
Hope this helps.
