How could you use universal indicator paper as a way of distinguishing between distilled water and sodium hydroxide solution and ethanoic acid solution?

Yes. Distilled water is neutral so would turn the paper green. Sodium hydroxide is an alkali so would turn the paper blue/purple. Ethanoic acid is an acid so would turn the paper red/orange.

What happens when sodium is added to water and universal indicator?
sodium will react violently with water, and end products are sodium hydroxide and hydrogen gas. the universal indicator would turn to around orange(?)
A hydroxide ion is indicated by?
As a chemical ion it is 'OH^-'. As in sodium hydroxide NaOH. A pH indicator will shown it as pH 8 to 12' depending on the ionic strength. A Universal Indicator will colour 'blue/violet/indigo'.
If universal indicator was added to the water after the reaction with caesium what colour would it go and why?
Caesium recats with water to form caesium hydroxide , a base. the universal indicator woulg change color to be brown/purple depending on the concentration i.e pH. see link
What colour does universal indicator turn in ammonia solution?
ammonium hydroxide is a basic or alkaline salt & phenolphthelin gives pink colour in basic medium because it is a basic indicator
If universal indicator was added to the water after the reaction with caesium what colour would it be?
Water is usually around pH7 so would turn Universal Indicator Green
How could you use universal indicator paper as a way of distinguishing between distilled water sodium hydroxide solution and ethanoic acid solution?
Yes. Distilled water is neutral so would turn the paper green. Sodium hydroxide is an alkali so would turn the paper blue/purple. Ethanoic acid is an acid so would turn the paper red/orange.
Why does sodium hydroxide turn universal indicator blue?
Because sodium hydroxide is an alkali with a high PH scale
Sodium hydroxide turns universal indicator blue because it is?
because it is an alkiline
What color is it when you put universal indicator into distilled water?
it changes into deep blue colour.
What colour should sodium be in universal indicator?
Purple. Sodium Hydroxide is an Alkali/base. Bases and Alkalis have a pH greater than 7, and turn blue-purple in universal indicator.
What happens when sodium is added to water and universal indicator?
sodium will react violently with water, and end products are sodium hydroxide and hydrogen gas. the universal indicator would turn to around orange(?)
What colour would universal indicator change with potassium hydroxide?
It would make it a blue color, meaning alkaline.
A hydroxide ion is indicated by?
As a chemical ion it is 'OH^-'. As in sodium hydroxide NaOH. A pH indicator will shown it as pH 8 to 12' depending on the ionic strength. A Universal Indicator will colour 'blue/violet/indigo'.
What color would you observe between milk of magnesia and universal indicator?
The color is blue because magnesia milk is a hydroxide.
What would be expected when sodium hydroxide solution is added gradually to a conical flask of dilute nitric acid containing universal indicator?
The indicator would show a rising pH.
When a drop of universal indicator is dropped into calcium hydroxide what colour change will you observe?
With a pH of 12 it is very alkaline and would turn universal indicator dark blue.
If universal indicator was added to the water after the reaction with caesium what colour would it go and why?
Caesium recats with water to form caesium hydroxide , a base. the universal indicator woulg change color to be brown/purple depending on the concentration i.e pH. see link
