What else can I help you with?
What is the pH value of universal indicator?
When it is not mixed with any other solution, it is green. Green represents neutrality, so its pH is 7.
What is the difference between an indicator and a universal indicator?
A pH meter uses a probe and voltmeter to measure pH digitally. Universal indicator is a mix of indicators that change colour to indicate the pH of the solution. pH meters are accurate and will detect changes quickly, whereas universal indicator is slow to change colour to indicate pH change.
Why is the universal indicator better than other indicators?
Because universal shows how strong or weak a substance is. Litmus just shows if its Alkaline or Acid. ps a 12 yr old wrote this.
What is universal indicator state the purpose for which this indicator is used?
Universal indicator is a mixture of dyes that changes color in response to different pH levels. It is used to determine the approximate pH of a solution by observing the color change of the indicator when added to the solution.
What if you test soda lime with a universal indicator would it register a pH above or below 7?
Soda lime should register a pH above 7 when tested with a universal indicator. Soda lime is a mixture of chemicals including calcium hydroxide, which is a strong base. Universal indicators change color in the presence of different pH levels, with colors shifting towards blue for bases.
What is the name of the indicator that gives you the range of colours for different pH numbers?
The indicator that gives you the range of colors for different pH numbers is called universal indicator. It is a mixture of several indicators that changes color over a wide pH range.
Universal indicator is a mixture of what?
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
Who invented the universal indicator?
The universal indicator was developed by Arnold J. Olsen in 1933. It is a mixture of several different indicators that change color over a wide range of pH levels.
What colour does an alkali go when in universal indicator?
An alkali usually turns purple or blue when in universal indicator. This is because universal indicator contains a mixture of different pH indicators that change color at various pH levels, with blue or purple indicating a high pH level associated with alkalis.
What will be the color of universal indicator in lemon juice?
The color of universal indicator in lemon juice will be red. Universal indicator is a mixture of different pH indicators that change color based on the acidity or alkalinity of a solution. Lemon juice is acidic due to its citric acid content, which will cause the universal indicator to turn red, indicating a low pH level.

What color is the color of universal indicator?
Universal indicator is typically a mixture of several indicators that change colors at different pH levels. It transitions through a variety of colors depending on the pH of the solution, ranging from red at low pH to violet at high pH.

Universal indicator is a mixture of dyes that changes color in response to different pH levels. It is used to determine the approximate pH of a solution by observing the color change of the indicator when added to the solution.

Soda lime should register a pH above 7 when tested with a universal indicator. Soda lime is a mixture of chemicals including calcium hydroxide, which is a strong base. Universal indicators change color in the presence of different pH levels, with colors shifting towards blue for bases.
When you put an alkali and Universal Indicator in a test tube what colour does it go?
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.
