It would make it a blue color, meaning alkaline.

When the reaction with potassium had finished what would happen if you added universal indicator solution to the water?

If you add universal indicator solution to the water after the reaction with potassium, the indicator will change color depending on the pH of the solution. Potassium reacts with water to form potassium hydroxide, which is a strong base. The solution will likely turn purple or blue indicating a high pH.


Would a soap solution test as a base with universal indicator paper?

Yes, a soap solution would test as a base with universal indicator paper as soaps are typically alkaline in nature due to the presence of sodium or potassium hydroxide. This would cause the universal indicator paper to change color to indicate its basic pH.


What happens when potassium hydroxide reacts with litmus paper?

Potassium hydroxide is a strong base that will turn red litmus paper blue, indicating its basic nature. The hydroxide ions in potassium hydroxide react with the indicator dye in the litmus paper, causing a color change.


Which gas turns a universal indicator blue?

The gas that turns a universal indicator blue is usually chlorine.


When a drop of universal indicator is dropped into calcium hydroxide what colour change will you observe?

Oh, dude, when you drop universal indicator into calcium hydroxide, you'll see a color change from purple or blue to a more vibrant purple or pink. It's like magic, but with chemicals. Just don't drink it thinking it's a fancy cocktail, okay?


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.


Is hydrochloric acid reacts with potassium hydroxide to produce a saltwater and heat a physical or chemical change?

The reaction of hydrochloric acid with potassium hydroxide is a chemical change because new substances (salt and water) are formed that have different chemical properties than the original reactants. The release of heat is an indicator of a chemical reaction taking place.


If you add alkali to water what colour would the water be?

Alkalis are bases dissolved in water. They do not have specific colours and are often colourless liquids.Indicators are used to determine the strength of an acid or alkali and change colour when exposed to the liquid.Look at Universal Indicator 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.


Why the indicator is not used when V ml of acid is added to potassium hydroxide to produce crystal?

The indicator is not used in this reaction because the reaction between an acid and potassium hydroxide is a neutralization reaction, where the acid and base completely react to form water and a salt. The endpoint is indicated by the formation of a solid precipitate or a color change due to the formation of the salt, so an indicator is not necessary.


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 colour does a universal indicator change to when it is mixed with a strong acid?

A universal indicator changes to red when mixed with a strong acid.
