The universal indicator changes color when added to lithium hydroxide (LiOH) because LiOH is a strong base that dissociates in water to produce hydroxide ions (OH⁻). The presence of these hydroxide ions increases the pH of the solution, making it more alkaline. The universal indicator responds to this change in pH by shifting to a color that reflects the basicity of the solution, typically turning from green (neutral) to blue or purple (alkaline).
What else can I help you with?
When a drop of universal indicator is added to water what is the colour change?
Pure water is neutral so the color will be green.
What colour does universe indicator with antacid solution?
The universe as a whole does not have a specific colour. However, in a science experiment, when an antacid solution is added to a universal indicator, it may change colour based on the pH level of the solution. This change in colour signifies the acidity or alkalinity of the solution.
What colour does universal indicator change to if bromine water is added?
When bromine water is added to a solution containing a universal indicator, the color change depends on the pH of the solution. Bromine water is typically acidic, so if the solution is neutral or basic, the universal indicator may shift towards red or orange, indicating a lower pH. In a strongly acidic environment, it would turn red. Overall, the specific color change can vary based on the existing pH of the solution.
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 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.
What colour does universal indicator change to if sodium sodium by carbonate is added?
Universal indicator changes to green when sodium bicarbonate is added.
What colour does universal indicator change to Hydrochloric acid is added?
Universal indicator changes to red/orange when hydrochloric acid is added, indicating that the solution is acidic.
What colour does acid turn when added to universal indicator?
When acid is added to universal indicator, the indicator will typically change to shades of red, orange, or yellow, depending on the strength of the acid.
What colour will milk become when universal indicator added?
When universal indicator is added to milk, it will change to a blue or purple color, indicating a basic pH level.
What colour does universal indicator change to if carbonate acid is added?
Universal indicator changes to a color in the green/blue range when carbonate acid is added. This indicates a basic or alkaline pH level.
What colour will a neutral solution become if a universal indicator was added?
A neutral solution added to universal indicator will turn green.
What colour does universal indicator turn when added to vinigar?
Universal indicator turns red when added to vinegar, indicating that the vinegar is acidic.
What colour does universal indicator change to if chlorine water is added?
Universal indicator will change to a bleaching effect color (yellow or yellow-green) when chlorine water is added due to the presence of hypochlorous acid.
When a drop of universal indicator is added to water what is the colour change?
Pure water is neutral so the color will be green.
What will be the colour of the universal indicator if it is added to a sample of egg yolk?
green.
