The universal indicator in an alkali solution typically turns a dark blue or purple color. This color change is due to the presence of hydroxide ions in the solution, which indicates a high pH level. The universal indicator is a mixture of different dyes that change color based on the pH of the solution, with blue or purple indicating a strong alkali.
What else can I help you with?
What is the material used to remove an indicator from a neutralized solution how does this work?
it is universal indicator with mixture of alkali
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 color do neutral solution turn the unniversal indicator?
A neutral solution will turn universal indicator green.
Which liquid or liquids caused the universal indicator to change colour?
The universal indicator changes color in response to the acidic or basic nature of a solution. Acidic solutions will turn the indicator to a red color, while basic solutions will turn it to a blue or purple color. Different liquids with varying pH levels can cause the universal indicator to change color accordingly.
Which chemical property of lithium will be shown by the universal indicator?
The chemical property of lithium that will be shown by the universal indicator is its ability to be an alkali metal. When lithium reacts with water, it forms lithium hydroxide, which is a strong base. This reaction will cause the universal indicator to turn blue or purple, indicating a basic pH.
What color would universal indicator in strong alkali?
red
What color did universal indicator if it is added to weak alkali?
blue
What is colour of universal indicator be in weak alkali?
In weak alkali, universal indicator will typically turn green or blue. The specific color will depend on the pH of the solution - the higher the pH, the bluer the color.
What effect does and alkali have on an universal indicator?
When an alkali is added to universal indicator, the color of the indicator will typically change to blue or purple, indicating a high pH. Alkalis are substances that have a pH above 7 and tend to turn universal indicator towards the blue end of the spectrum.
What colour does when universal Indicator goes in alkali?
When universal indicator is added to an alkali, it typically turns dark purple or dark purple-blue in color. This indicates a high pH level in the solution.
What colour does universal indicator go in a alkali?
Universal indicator turns shades of blue or purple in an alkali.
What colour will universal indicator turn when acid is mixed with alkali?
Universal indicator will turn green when an acid is mixed with an alkali. This green color indicates a neutral pH level which is achieved when the acid and alkali have neutralized each other.
What colour would universal indicator be in a strong alkali?
Universal indicator would be dark blue or purple in a strong alkali.
What colour will universal indicator turn when mixed with a weak alkali?
Universal indicator will turn purple or blue when mixed with a weak alkali.
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 coulour does universal indicator turn when mixed with strong alkali?
Universal indicator turns deep blue or violet when mixed with a strong alkali.
What colour an alkali comes out with a universal indicator?
Blue/Violet/Indigo . depending on the strength of the alkali. Water (neutral ) is green Acids ' Red/Orange/Yellow.
