Purple. Sodium Hydroxide is an Alkali/base. Bases and Alkalis have a pH greater than 7, and turn blue-purple in universal indicator.
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
When just enough acid has been added to neutralize the sodium hydroxide what colour will the indicator be?
Green
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.

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'.
Sodium hydroxide turns universal indicator blue because it is?
because it is an alkiline
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(?)
When just enough acid has been added to neutralize the sodium hydroxide what colour will the indicator be?
Green
What happens to the indicator when hydrochloric acid is added to sodium hydroxide?

Which colour is produced when universal indicator is added to sodium bicarbonate?
Baking soda is sodium bicarbonate or sodium hydrogen carbonate It is alkaline and will therefore turn universal indicator purple or blue
What colour is sodium chloride in a universal indicator?
It has a pH of 7, meaning it's neutral. It would be Green on a universal indicator.
