Universal indicator is a solution composed of several different indicators, each of which changes color at different pH levels. The pH scale is a way to measure the acidity or alkalinity of a substance based on its concentration of hydrogen ions. Universal indicator's color change corresponds to different pH levels, making it a useful tool for determining the pH of a substance.

Universal indicator is mostly preferred over litmus indicator why?
Universal indicator covers a wider pH range compared to litmus indicator, which only detects acidic or basic conditions. Universal indicator provides a more precise indication of the pH level of a solution by producing a range of colors across the pH scale.
What word describes a chemical which turns universal indicator green?
Neutral is a word that describes a chemical which turns a universal indicator green. This chemical has a pH equal to 7.0 on the pH scale.
How is the pH of a solution is measured using universal indicator?
The pH of a solution is measured using universal indicator by adding a few drops of the indicator to the solution and observing the color change. The color of the solution corresponds to the pH level on the universal indicator color scale, which ranges from red (acidic) to purple (neutral) to blue (basic).
Is a universal indicator a mixture of 4 different indicators?
A universal indicator is a mixture of several indicators, typically about 10, that have different colors at different pH levels. This mixture allows the universal indicator to display a different color for each pH level across the entire pH scale.
What is the difference between an indicator and a universal indicator?
An indicator is a substance that changes color in response to changes in pH, indicating the acidity or alkalinity of a solution. A universal indicator is a mixture of indicators that can show a range of pH levels by changing color, making it more versatile than a single indicator.
What is the short term for universal indicator?

What liquid do you use to test the pH scale?
A pH testing liquid called universal indicator solution is commonly used to test the pH scale. It changes color depending on whether the substance is acidic, neutral, or basic.

How do you know what a acid or a alkali is?
You use a universal indicator and it turns into whatever colour, according to the PH scale.
What is the difference between an indicator and a universal indicator?

Why turns universal indicator light green?
Universal indicator turns green because it indicates a neutral pH level, which is typically around 7 on the pH scale. In this range, the indicator changes color to green to show a balance between acidity and alkalinity in the solution.
What colour is universal indicator solution when you put acid in?
Universal indicator solution turns a shade of red, orange, or yellow when added to an acidic solution.
What does yellow indicate on the ph scale?
It depends on what indicator you are using. Yellow with the bromothymol blue indicator is acidic, yellow with the methyl orange indicator is basic, yellow with the phenol red indicator is acidic and yellow with the universal indicator is acidic.
What happens when you add universal indicator to sulfuric acid?
When universal indicator is added to sulfuric acid, the solution will turn red as sulfuric acid is a strong acid. It indicates a highly acidic pH level in the solution.
