What colour is sodium hydroxide when you add universal indicator?
When you add universal indicator to sodium hydroxide, it will typically turn purple or dark blue in color, indicating that the solution is strongly alkaline.
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.
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.
Which gas turns a universal indicator blue?
The gas that turns a universal indicator blue is usually chlorine.
What would be expected when sodium hydroxide solution is added gradually to a conical flask of dilute nitric acid containing universal indicator?
The sodium hydroxide will neutralize the nitric acid, resulting in a color change of the universal indicator from red to purple to blue, indicating the solution is becoming more basic. This reaction will also generate heat due to the exothermic nature of the neutralization reaction.

Purple. Sodium Hydroxide is an Alkali/base. Bases and Alkalis have a pH greater than 7, and turn blue-purple in universal indicator.
What turns universal indicator blue?
A base turns the universal indicator blue or u can say a alkali substance.
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.
Universal indicator is a mixture of what?
Universal indicators can be mixed with different substances. Universal indicators usually contain water, salt, propan-1-ol, sodium hydroxide, monosodium, phenolphthalein sodium salt, methyl red, bromothymol blue, and thymol blue monosodium salt
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'.
Which gas turns a universal indicator blue?
The gas that turns a universal indicator blue is usually chlorine.

What turns sodium hydroxide blue?
substances with a pH of less than 7 are acidsthe stronger the acid, the lower the pH numberacids turn blue litmus paper redthey turn universal indicator red if they are strong, and orange or yellow if they are weak
Color of sodium carbonate in universal indicator?
Sodium carbonate in universal indicator will typically appear blue or purple in color. This is due to the alkaline nature of sodium carbonate, indicating a high pH level.
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
