It would make it a blue color, meaning alkaline.
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.
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.
The gas that turns a universal indicator blue is usually chlorine.
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?
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 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.

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.

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.
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.
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.
Universal indicator changes to green when sodium bicarbonate is added.
A universal indicator changes to red when mixed with a strong acid.
