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.
When universal indicator is added to lime juice, it typically turns a reddish color, indicating that the lime juice is acidic. Lime juice is high in citric acid, which is why it produces this reaction with the indicator.
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.
Limewater is an indicator for Carbon Dioxide
When a drop of phenolphthalein is introduced in lime water the solution turns pink in colour.
The color is pink with phenolphthalein.
When universal indicator is added to lime juice, it typically turns a reddish color, indicating that the lime juice is acidic. Lime juice is high in citric acid, which is why it produces this reaction with the indicator.
The color is blue to violet.
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.

When a drop of phenolphthalein is introduced in lime water the solution turns pink in colour.
The color is pink with 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.
Chemical indicators that detect carbon dioxide include bromothymol blue, phenol red, and pH-sensitive dyes like universal indicator. These indicators change color in the presence of carbon dioxide due to a change in pH levels.
Lime water typically burns with a yellow or greenish flame.
Lime water (calcium hydroxide) turns milky/cloudy when exposed to carbon dioxide due to the formation of calcium carbonate, which is insoluble. This property makes it a useful indicator for the presence of carbon dioxide in a substance or a gas.
In the experiment of anaerobic respiration of yeast, the yeast ferments sugars and produces carbon dioxide as a byproduct. When carbon dioxide is bubbled through lime water (calcium hydroxide solution), it reacts to form calcium carbonate, which causes the lime water to turn cloudy. If a hydrogen carbonate indicator solution is used, the increase in carbon dioxide leads to a color change, typically becoming more acidic and resulting in a shift in color depending on the pH change. This indicates the production of carbon dioxide during yeast fermentation.
Lime water changes from clear to milky/cloudy when carbon dioxide is bubbled in, indicating the formation of calcium carbonate.
