What colour would universal indicator be in caustic soda?
Universal indicator would turn dark blue or purple in caustic soda, indicating a high pH level.
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 colour would the universal indicator go in washing soda with water?
When washing soda (sodium carbonate) is dissolved in water, it creates an alkaline solution. The universal indicator would turn blue to purple, indicating a pH level typically above 9. This color change signifies the basic nature of the washing soda solution.
What is the colour of universal indicator solution in a neutral solution?
The Universal Indicator would go green which is pH 7.
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.
What colour would universal indicator be in a strong alkali?
Universal indicator would be dark blue or purple in a strong alkali.
Would universal indicator turn purple in a strong alkali?
no i think
What colour would you espect universal indicator to turn in a strong acid?
It would turn red in strong acid, orange/yellow in a weak acid, green in a neutral solution, blue in a weak base and purple in a strong base
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 should sodium be in universal indicator?
Purple. Sodium Hydroxide is an Alkali/base. Bases and Alkalis have a pH greater than 7, and turn blue-purple in universal indicator.
What colour would universal indicator change with potassium hydroxide?
It would make it a blue color, meaning alkaline.
What color would universal indicator in strong alkali?
red
What colour would universal indicator turn in soil containing alkaline?
Universal indicator would turn blue or purple in soil containing alkaline.
What colour would universal indicator be in caustic soda?
Universal indicator would turn dark blue or purple in caustic soda, indicating a high pH level.
If universal indicator was added to the water after the reaction with caesium what colour would it be?
The universal indicator in water after the reaction with cesium would likely turn purple. Universal indicator changes color to purple in the presence of strong bases like cesium hydroxide, which would be formed as a result of the reaction with cesium and water.
What colour is sodium chloride in a universal indicator?
Sodium chloride is a neutral substance and will not exhibit a specific color in a universal indicator. Universal indicators change color based on the pH of a solution, not the presence of specific compounds like sodium chloride.
When the reaction with potassium had finished what would happen if you added universal indicator solution to the water?
If you add universal indicator solution to the water after the reaction with potassium, the indicator will change color depending on the pH of the solution. Potassium reacts with water to form potassium hydroxide, which is a strong base. The solution will likely turn purple or blue indicating a high pH.
