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 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.
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 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.
Does sodium hydroxide turn litmus solution purple?
yes, it turns in purple or a very light pink-ish purple color
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 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.
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 happen when sodium hydroxide is added drop wise to a solution containing phenolphthalein?
When sodium hydroxide is added dropwise to a solution containing phenolphthalein, the solution will initially remain colorless. Once enough sodium hydroxide has been added to make the solution basic, the color will change from colorless to pink or purple, indicating the presence of hydroxide ions. Phenolphthalein is a pH indicator that changes color in the presence of a base.
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.
Does sodium hydroxide turn litmus solution purple?
yes, it turns in purple or a very light pink-ish purple color
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 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 when methyl orange is added to sodium hydroxide?
When methyl orange is added to sodium hydroxide, the color of the solution changes from red (acidic) to yellow (basic). This indicates that the solution has become more alkaline due to the reaction between the sodium hydroxide and the indicator. Methyl orange is an acid-base indicator that changes color based on the pH of the solution.
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.
Is sodium hydroxide a base or acid how will you justify?
Sodium hydroxide is a strong base. This can be justified by the fact that when it dissociates in water, it releases hydroxide ions (OH-) which can accept protons (H+) and increase the pH of the solution.
Is sodium hydroxide unknown solution?
Sodium hydroxide is not an unknown solution.
