What color would phenoplhthalein turn if drano was added?
Phenolphthalein would turn pink when added to Drano, which is a strong alkaline substance. This color change indicates that the solution has become basic.
What happened to the color of bromothymol blue turn when HCI and NaOCI are added?
When HCl is added to bromothymol blue, the solution turns yellow due to the increased acidity. When NaOCl (sodium hypochlorite) is added, the color changes to green or blue, indicating the basic pH of the solution due to the formation of hypochlorous acid.
Why does litmus turn purple in neutral solutions?
Litmus paper turns purple in neutral solutions because it contains a pH-sensitive dye that changes color based on the acidity or alkalinity of the solution. In neutral conditions, with a pH around 7, the dye in litmus paper exhibits a purple color due to the balance of hydrogen and hydroxide ions. This color change indicates that the solution is neither acidic nor basic.
What is the colour of phenolphthalein in salt water?
It will turn purple
What color does phenopthaline turn to?
In acid, phenylphthalein is colorless; however, in a basic solution, it is a pinkish to purple color. Therefore it is useful in determining whether a solution is acidic or basic.
When neutral litmus solution is added to alkaline solution?
When neutral litmus solution is added to an alkaline solution, the litmus solution will turn blue. This change in color indicates that the solution is basic or alkaline in nature. Litmus paper is commonly used as an indicator to determine the acidity or alkalinity of a solution.
What color does litmus paper turn when it is nuetral?
In a neutral solution litmus has a purple color.
What color does biuret reagent turn if lipid is present?
If lipids are present, the solution will turn a purple/violet color.

What color does base turn a universal indicator?
The color of a universal indicator in a basic solution is usually purple or blue.
What will be the color of phenolphthalein when added to a solution of hydroxide?
Phenolphthalein will turn pink or magenta in color when added to a basic solution containing hydroxide ions.
What color does an acid turn if red cabage indacator is added?
Acids turn red/pink when red cabbage indicator is added. Alkali/bases turn blue/green. Neutrals turn purple.
What color does Biuret turn in the presence of protein?
purple
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.
What colour does bleach turn in universal indicator?
Bleach is a basic solution, so it will turn universal indicator to a purple color. This indicates a high pH level in the bleach solution.
What color would phenoplhthalein turn if drano was added?
Phenolphthalein would turn pink when added to Drano, which is a strong alkaline substance. This color change indicates that the solution has become basic.
