Why does the indicator goes purple in sodium hydroxide solution?
The purple color in sodium hydroxide solution is an indicator of the presence of phenolphthalein, which turns pink in basic solutions. When phenolphthalein is added to sodium hydroxide solution, it reacts with the hydroxide ions in the solution to form the purple color.
How to distinguish sodium hydroxide solution and ammonium hydroxide solution by a chemical test?
Chemical Test for Solutions Default (GPT-3.5) User How to distinguish sodium hydroxide solution and ammonium hydroxide solution by a chemical test? ChatGPT You can distinguish between sodium hydroxide (NaOH) solution and ammonium hydroxide (NH4OH) solution using a simple chemical test. Litmus Paper Test: Dip a piece of red litmus paper into each solution. Sodium hydroxide (NaOH) is a strong base and will turn red litmus paper blue. Ammonium hydroxide (NH4OH) is a weak base and will also turn red litmus paper blue, but it may do so less vigorously and may take some time. Phenolphthalein Test: Add a few drops of phenolphthalein indicator to each solution. Sodium hydroxide (NaOH) will turn pink or magenta, indicating its strong alkaline nature. Ammonium hydroxide (NH4OH) may turn pink, but it will be less intense, indicating its weaker alkaline properties. Odor Test: Carefully smell the solutions. Ammonium hydroxide (NH4OH) solution has a distinctive, pungent ammonia-like odor, which is not present in sodium hydroxide (NaOH) solution.
What color does blue litmus paper turn with Sodium hydroxide?
NOTHING! Sodium hydroxide (NaOH) is a base, and BLP does not change color with a base.
Why does red litmus paper turn blue in sodium hydroxide if it is acid'?
Red litmus paper turns blue in sodium hydroxide because the red litmus paper is indicating the presence of acidity. When it comes into contact with sodium hydroxide, a strong base, the base neutralizes the acid on the litmus paper, causing the color change to blue.
What colour is sodium hydroxide in universal indicator?
Sodium hydroxide turns Universal Indicator solution dark purple, indicating it is a strong base with a high pH level.
What do you observe when red litmus is added to a solution of sodium sulphate?
Sodium sulfate solution is neutral; the red litmus is purple.
Why does the indicator goes purple in sodium hydroxide solution?
The purple color in sodium hydroxide solution is an indicator of the presence of phenolphthalein, which turns pink in basic solutions. When phenolphthalein is added to sodium hydroxide solution, it reacts with the hydroxide ions in the solution to form the purple color.
What is the action of sodium hydroxide on the colour of red litmus?
Sodium hydroxide is a strong base and will turn red litmus paper blue. This color change occurs due to the high concentration of hydroxide ions present in the sodium hydroxide solution, which react with the indicator dye in the litmus paper, causing the color change.

Colour of sodium hydroxide of litmus?
Sodium hydroxide turns red litmus paper blue.
What will be the effect of sodium hydroxide in blue litmus paper?
Sodium hydroxide is a strong base, so it will turn blue litmus paper to red. This color change is due to the alkaline nature of sodium hydroxide which reacts with the blue litmus paper to change its color.
What color does blue litmus paper turn with Sodium hydroxide?
NOTHING! Sodium hydroxide (NaOH) is a base, and BLP does not change color with a base.

What reaction can be performed to tell the difference between sodium chloride and sodium hydroxide?
A litmus test is one way of comparing. Sodium Chloride is a neutral salt and so would have no effect on litmus. Sodium Hydroxide is a base, and would turn litmus blue.
Does sodium hydroxide turns blue litmus red?
no it does not
Is sodium hydroxide unknown solution?
Sodium hydroxide is not an unknown solution.
What colour is sodium hydroxide in universal indicator?
Sodium hydroxide turns Universal Indicator solution dark purple, indicating it is a strong base with a high pH level.
