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 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 colour would universal indicator change with potassium hydroxide?
It would make it a blue color, meaning alkaline.
What colour would universal indicator turn in soil containing alkaline?
Orange! Yah Your WELCOME!

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.

Orange! Yah Your WELCOME!
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.
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
How do you decide which of a group of solutions has the greatest concentration of hydroxide ions OH-?
To determine the pH of a range of solutions, you can use a pH meter, or a universal indicator.
When was universal indicator invented?
The universal Indicator was invented in 1923 by Yamada
