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.
Because sodium hydroxide is an alkali with a high PH scale
because it is an alkiline
Purple. Sodium Hydroxide is an Alkali/base. Bases and Alkalis have a pH greater than 7, and turn blue-purple in universal indicator.
It would make it a blue color, meaning alkaline.
The indicator would show a rising pH.

Because sodium hydroxide is an alkali with a high PH scale
because it is an alkiline
it changes into deep blue colour.

sodium will react violently with water, and end products are sodium hydroxide and hydrogen gas. the universal indicator would turn to around orange(?)
It would make it a blue color, meaning alkaline.
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'.
The color is blue because magnesia milk is a hydroxide.
The indicator would show a rising pH.
With a pH of 12 it is very alkaline and would turn universal indicator dark blue.
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
