Having just done an experiment in class I think I can answer this. In a test tube collect some swimming pool water then add some bromthymol blue and phenolphthalein and using pH paper dip it in the solution to determine the pH.
It will turn purple
The solution of carbon dioxide in water is colorless.
That depends on your tap water. Here where I live, the water is soft so its pH is quite low, 6.5 or 7, which means phenolphthalein is colourless. In some places it can be much higher, particularly where there is a lot of temporary hardness. Water companies work to the standard that pH should not exceed 9.5. Phenolphthalein changes colour over the range 8.2 to 10, so in very hard water it might show some pink.
To make a 1% solution of phenolphthalein, you would typically dissolve 1g of phenolphthalein in 100mL of a suitable solvent, such as ethanol or water. Mix well until the phenolphthalein is fully dissolved to obtain the desired concentration.
Phenolphthalein turns pink in the presence of a base or any solution with a ph over 7.
When water is added to phenolphthalein, the color remains the same, which is colorless. Phenolphthalein is typically used as an indicator in titrations with strong acid and strong base where the color change is triggered by changes in pH, not by the addition of water.
Yes, it is.
The color is pink with phenolphthalein.
Phenolphthalein dissolves in water because it is a water-soluble compound. The molecule has hydroxyl groups that can form hydrogen bonds with water molecules, allowing it to dissolve readily in water. Additionally, phenolphthalein is often used as a pH indicator in aqueous solutions due to its solubility in water.
When a drop of phenolphthalein is introduced in lime water the solution turns pink in colour.
Nothing, it is insoluble in water surface.
Ammonia gas get dissolved in water which form ammonium hydroxide. NH4OH is alkaline in nature. so when phenolphthalein is added to it. It produce PINK colouration.
Dissolve 0.1g of the powder in ethanol and dilute with distilled water upto 100 cm3
Phenolphthalein is colorless in tap water, as tap water is typically neutral to slightly acidic. It only turns pink in basic solutions with a pH above 8.2.
It will turn purple
The solution of carbon dioxide in water is colorless.
Yes, the color become pink.
