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 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 will appear when hydrochloric acid react to sodium hydroxide with a few drop of universal indicator?
A green colour will appear due to the reaction of hydrochloric acid and sodium hydroxide. The universal indicator changes color in response to the pH level of the solution, and green indicates a neutral pH level.
What colour does universal indicator change to if sodium sodium by carbonate is added?
Universal indicator changes to green when sodium bicarbonate is added.
Why does sodium hydroxide turn universal indicator blue?
When sodium hydroxide is added to universal indicator solution, it causes the indicator to turn blue because sodium hydroxide is a strong base. The blue color represents a high pH level, indicating that the solution has become more alkaline due to the presence of hydroxide ions released by the sodium hydroxide.
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 colour should sodium be in universal indicator?

Universal indicator changes to green when sodium bicarbonate is added.
Why does sodium hydroxide turn universal indicator blue?
When sodium hydroxide is added to universal indicator solution, it causes the indicator to turn blue because sodium hydroxide is a strong base. The blue color represents a high pH level, indicating that the solution has become more alkaline due to the presence of hydroxide ions released by the sodium hydroxide.
What colour should sodium sulphate be in universal indicator?
Sodium sulfate is typically colorless in universal indicator. Universal indicator is a pH indicator that changes color based on the pH of a solution, and sodium sulfate is a neutral compound that does not significantly affect the pH.
Sodium hydroxide turns universal indicator blue because it is?
Sodium hydroxide is a strong base that dissociates completely in solution to produce hydroxide ions. The presence of hydroxide ions in a solution turns universal indicator blue, indicating a high pH or alkaline condition.
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 happens when sodium is added to water and universal indicator?
When sodium is added to water, it reacts vigorously, releasing hydrogen gas and forming sodium hydroxide. The solution will become alkaline due to the formation of sodium hydroxide. When universal indicator is added, it will change color to indicate a high pH level, typically turning purple or blue for strong alkaline solutions.
What happens to the indicator when hydrochloric acid is added to sodium hydroxide?
It turns from its original blue colour to red.
What colour should sodium bicarbonate be in universal indicator?
Sodium bicarbonate would turn blue or purple in universal indicator solution, indicating a basic pH level, around pH 9-10.
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
