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 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.
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.
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 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.
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 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 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.
What turns universal indicator blue?
A base turns the universal indicator blue or u can say a alkali substance.
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.
What color will the indicator be in a neutral sodium hydroxide?
the indicator will be the pale colors of green :)
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.
What colo is PHTH in Sodium Hydroxide?
Phenolphthalein turns pink in basic solutions
