What else can I help you with?
Could universal indicator be used to identify a liquid as being pure water?
A pH indicator is used only to measure the pH of the solution.
What color does universal indicator turn in deionized water?
since water is pretty neutral, the water does not change color but the universal indicator does. The universal indicator changes color as per the quantity of deionized water... But it changes to straw color or pale yellow in 50mL of deionized water.
What colour will salt water go in universal indicator?
Salt water typically forms a neutral pH solution, so it will likely appear green in universal indicator.
What happens to water when the universal indicator is added to it?
It will become orange because CO2 is an acid
What is a water colour with universal indicator?
A watercolour with a universal indicator is a solution that includes a pH indicator that changes color depending on the acidity or alkalinity of the water. Universal indicators typically range from red in acidic conditions (pH < 7) to green at neutral (pH 7) and blue/purple in alkaline conditions (pH > 7). When mixed with water, this indicator provides a visual representation of the water's pH level, allowing users to assess its chemical properties easily. It is often used in educational settings to demonstrate pH testing and the effects of different substances on water quality.

What colour does water turn in the universal indicator?
Water typically turns green in universal indicator. This indicates that water is neutral, neither acidic nor basic.
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 color do alkalis turn universal indicator?
When universal indicator is put in water soluion of alkalis (base) it indicates significant blue colour.
What happens when you mix water with a universal indicator?
When water is mixed with a universal indicator, it will change color based on the pH of the water. Universal indicator contains a mixture of dyes that change color in response to different pH levels, allowing you to determine if the water is acidic, neutral, or basic.
What colour will salt water go in universal indicator?
Salt water typically forms a neutral pH solution, so it will likely appear green in universal indicator.
What happens to water when the universal indicator is added to it?
It will become orange because CO2 is an acid
When was universal indicator invented?
The universal Indicator was invented in 1923 by Yamada
What happens when you add universal indicator to water?
When universal indicator is added to water, it will change color based on the pH of the water. Universal indicator shows a range of colors corresponding to different pH levels, such as red for acidic solutions, green for neutral solutions, and blue/purple for basic solutions. This color change allows you to determine the approximate pH of the water.
Why was universal indicator paper used to test the pH rather than placing universal indicator solution into the mixture?
Use of paper avoid the contamination of the sample.
Which gas turns a universal indicator blue?
The gas that turns a universal indicator blue is usually chlorine.
