The Universal Indicator would go green which is pH 7.
What colour would the universal indicator turn with toothpaste?
This is because the toothpaste has some amount of acid or alkaline in it .
What is the specific name of universal indicator?
A Universal indicator is a pH indicator composed of a solution of several compounds that exhibits several smooth colour changes over a pH value range from 1-14 to indicate the acidity or basicity of solutions. A universal indicator is typically composed of water, propan-1-ol, phenolphthalein sodium salt, sodium hydroxide, methyl red, bromothymol blue monosodium salt, and thymol blue monosodium salt.
If universal indicator was added to the water after the reaction with cesium what colour would it go and why?
If universal indicator is added to water after a reaction with cesium, the solution would likely turn purple or dark blue. This is because cesium reacts vigorously with water to produce cesium hydroxide, which is a strong base. The formation of this alkaline solution raises the pH, causing the universal indicator to shift toward the color that corresponds to higher pH levels.
What universal indicator colour would bicarbonate of soda go?
Bicarbonate of soda, or sodium bicarbonate, is a basic substance. When tested with universal indicator, it would generally turn green to blue, indicating a pH level above 7, typically around 8 to 9. This reflects its alkaline nature, as it can neutralize acids.
What colour would universal indicator be in a strong alkali?
Universal indicator would be dark blue or purple in a strong alkali.
What colour would universal indicator turn in ethanol?
Universal indicator would likely turn red in ethanol, indicating that it is acidic.
What is colour of ethanol in universal indicator?
Universal indicator changes color in different pH ranges. In the case of ethanol, which is pH-neutral, universal indicator would likely show a green color.
What colour would an acid turn if mixed with water and universal indicator?
red
What colour does citric acid turn an universal indicator?
Citric acid is a weak acid, so it would turn a universal indicator to orange or red.
What colour would universal indicator turn in soil containing alkaline?
Universal indicator would turn blue or purple in soil containing alkaline.
What is the colour of universal indicator solution in a neutral solution?
The Universal Indicator would go green which is pH 7.
What colour would ammonia gas turn universal indicator paper?
Ammonia gas would turn universal indicator paper blue or purple depending on the concentration of ammonia present.
What colour would orange juice be in Universal indicator?
Orange juice would be acidic in nature, so it would likely turn red or pink in Universal indicator due to its low pH level.
What colour should weak acid be in a universal indicator?
A weak acid would typically be a shade of orange or red in universal indicator, indicating a pH of around 4-6.
What colour would a weak alkali turn in Universal Indicator?
A weak alkali would typically turn blue or purple in Universal Indicator, indicating a pH around 8-10.
Why would it be difficult to test a cup of coffee with universal indicator?
Because Coffee is a dark colour and if your testing it with universal indicator paper the paper might stain from the strong coffee colour and not be entirely accurate. I have never tried this personally its just as assumption.
