What colour appear when lime water plus phenolphthalein?
When lime water (a solution of calcium hydroxide) is mixed with phenolphthalein, the solution turns pink. This occurs because phenolphthalein is a pH indicator that changes color in basic solutions. Lime water is alkaline, so it causes the phenolphthalein to shift from colorless to pink in the presence of a base.
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.
How does the type of indicator affect the pH?
Each indicator has a specific change of color when the pH is changed.
What is it called when a substance changes color in response to pH?
This is a pH indicator.
What is a chemical dye that changes color based on the pH of a solution called?
A chemical dye that changes color based on the pH of a solution is called an pH indicator.
When a drop of phenolphthalein is introduced in lime water the solution turns?
When a drop of phenolphthalein is introduced in lime water the solution turns pink in colour.
What will be the color of universal indicator in lime water?
Oh, dude, lime water is basic, so the universal indicator will turn purple because it's like, "Whoa, this is basic stuff." So yeah, when it sees lime water, it's all like, "Purple, baby!" Just a heads up, don't expect it to throw a party or anything.
What color does coconut water turn a indicator?
Coconut water typically turns a pH indicator red or pink if the indicator is phenolphthalein, which indicates a neutral to slightly acidic pH. However, if a universal pH indicator is used, coconut water generally shows a color around green, indicating a pH close to neutral (around 6-7). The exact color can vary depending on the specific pH indicator used and the coconut water's composition.
Why does cabbage indicator stay the same colour in water?
Cabbage indicator stays the same color in water because water has a neutral pH, which does not cause the indicator to change its color. The pigment in cabbage indicator changes color in response to changes in the pH level of its environment, but since water has a pH level close to 7 (neutral), there is no significant change in color.
What colour appear when lime water plus phenolphthalein?
When lime water (a solution of calcium hydroxide) is mixed with phenolphthalein, the solution turns pink. This occurs because phenolphthalein is a pH indicator that changes color in basic solutions. Lime water is alkaline, so it causes the phenolphthalein to shift from colorless to pink in the presence of a base.
What if you test soda lime with a universal indicator would it register a pH above or below 7?
Soda lime should register a pH above 7 when tested with a universal indicator. Soda lime is a mixture of chemicals including calcium hydroxide, which is a strong base. Universal indicators change color in the presence of different pH levels, with colors shifting towards blue for bases.
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.
Pure water turns universal indicator greenwhat PH does this indicate?
A green color on universal indicator typically indicates a pH of around 7, which is neutral. In this case, the pure water has a pH close to neutral.
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.
How does the type of indicator affect the pH?
Each indicator has a specific change of color when the pH is changed.
What does universal indicator test for?
A universal indicator changes color in response to the pH of a liquid. Do determine the pH of the liquid, you need to refer to a color chart that tells you which color indicates which pH.
What happens to water when add indicator?
water is pretty neutral in terms of the pH scale, so nothing should happen unless you have poisoned water .It'll turn green if you used universal indicator(pH7), after you added it, the water is posioned you can't drink it
