When an alkali is added to a test tube containing Universal Indicator, it typically turns the indicator solution a dark green or blue color. This is because Universal Indicator is a mixture of different pH indicators that show a range of colors from red (acidic) to green (neutral) to blue or purple (alkaline). The specific color change observed may vary depending on the concentration and type of alkali used.
A universal indicator is an indicator that changes color along with changes in pH level. The purpose of using it is to find a point at which a mixture of acid and base becomes neutral.

An Universal Indictator is more helpful because it shows the exact amount of acidity. Other indictators (example the red and blue litmus) just indicates whether or not the solution is acidic. The universal indicator gives you a specific color to which you can match a pH number therefore, telling you how acidic the soultion is.
Hi, just looked this up, here's something to show you how universal indicators work:Universal indicator and the pH scaleUniversal indicator is a mixture of several different indicators. Unlike litmus, universal indicator can show us exactly how strongly acidic or alkaline a solution is. This is measured using the pH scale. The pH scale runs from pH 0 to pH 14.Universal indicator has many different colour changes, from red for strong acids to dark purple for strong bases. In the middle, neutral pH 7 is indicated by green.Universal indicator shows how acidic or alkaline a solution isThese are the important points about the pH scale:neutral solutions are pH 7 exactlyacidic solutions have pH values less than 7alkaline solutions have pH values more than 7the closer to pH 0 you go, the more strongly acidic a solution isthe closer to pH 14 you go, the more strongly alkaline a solution is
Universal indicators can be mixed with different substances. Universal indicators usually contain water, salt, propan-1-ol, sodium hydroxide, monosodium, phenolphthalein sodium salt, methyl red, bromothymol blue, and thymol blue monosodium salt

Use of paper avoid the contamination of the sample.
No totally different, universal indicator is a mixture of chemical which shows the precise p.H of a substance, blue litmus paper reveals whether the substance is acidic or alkaline.

We measure pH by using a pH scale which has different colours on it which indicates the liquid. Universal indicator is a pH indicator that transitions through numbers 1- 14 (on a pH chart) to indicate the acidity or alkali of solution. A pH meter is an electric instrument used to measure the pH of a liquid which might be an acid neutral or an alkali. and there is my answer Lewis Jones park community school lots of substances change colour at specific pH values, so you have to use a colour chart for that specific substance. Universal indicator is a mixture of lots of different indicators so it changes colour many times throughout the entire pH range, and you can compare it to the universal indicator colour chart to find how acidic or alkaline your substance is.

I don't know what you mean by "universal indicator". That's a generic term for a mixture of indicators that displays distinct colors over a fairly broad pH range, but without knowing which specific one you're using it's difficult to say. However, a lot of them are minor variations on Yamada's 1923 patent, so I'd expect that it would probably be somewhere in the greenish part of the spectrum. Exactly where depends on the particular ratios of the various indicator compounds used.
it is universal indicator with mixture of alkali
