What is the point at which a base permanently changes the color of an acid solution?
Acidity does not in itself have any color, and there is no specific pH at which a solution will necessarily change color (temporarily or permanently) however, there are some chemicals called indicators which can be added to a solution in order to create colors that will react to changes in pH. Since there are a number of different indicators that you can use, again there is no specific pH, it depends upon what you are using.

What is the name for the point at which the indicator changes color in a titration?
The point at which the indicator changes color in a titration is called the "endpoint". It signifies the completion of the reaction between the titrant and analyte in the solution being titrated.
What color will a solution be at the equivalence point of titration?
The color of a solution at the equivalence point of a titration depends on the type of indicator used. The indicator changes color at a specific pH value, signaling the completion of the reaction. Common indicators like phenolphthalein turn pink at the equivalence point of an acid-base titration.
What is the name for the point at which the indicator changes color in a titration?
The point at which the indicator changes color in a titration is called the endpoint.
What happens during an acidic base titration in the presents of an indication?
During an acid-base titration, an indicator is added to the solution to determine the endpoint, which is when the moles of acid are equal to the moles of base. The indicator changes color at the endpoint, indicating the completion of the reaction. This color change helps in identifying the point of neutralization and determining the concentration of the unknown solution.
In a titration when does the indicator change color?
when the equivalence point of a titration is achieved.. Added: (More precisely:) The equivalence point is the point where the number of moles of base equal the number of moles of acid. The end point is the point where the indicator being used changes color (also 'indication point)'. If the indicator is chosen correctly, the end point will essentially be exactly as near as possible at the equivalence point. The point of the titration is to find the equivalence point -- the end point is just a very close approximation to it. This is because the pH of the solution changes very rapidly close to the equivalence point. Therefore, the indicator will change color very close to the equivalence point because of the steepness of the pH change

The point at which a drop of base changes the color of an acid solution and the color persists?
This point is known as the endpoint in a titration. It signifies that the reaction between the acid and base is complete. The color change usually happens due to the addition of an indicator, which changes color at a specific pH.

What is a rocks name with rainbow crystals inside it?
Phantom quartz crystal, they form from changes in solution as the point is growing in the limestone strata, as the mineralization changes so dose the color of the phantom coated point in the point, and so on tell the solution aquifer has stop flow of sediment in solution. Many times if a stone shows a prism or rainbow effect. The stone is cracked. You are seeing the prism effect reflections. Pretty. But unstable.
What happens to the color of the FeCl2 when the equivalence point is reached?
FeCI2 is a combination of iron and hydrochloride. This solution starts out as a yellowish green color. When the equivalence point is reach the solution turns to an orange brown color.

Changes color at the endpoint of titration?
The color change at the endpoint of a titration is due to the indicator used in the titration process. The indicator changes color based on the pH of the solution, signaling the completion of the reaction between the analyte and titrant. This color change helps determine the equivalence point of the titration.
How do you tell if you have exceeded equivalence point in titration?
You have exceeded the equivalence point in a titration when the indicator you are using changes color permanently, indicating that one of the reactants is present in excess. This indicates that the moles of the titrant added are greater than the moles needed to react completely with the analyte.
How can one determine the boiling point of a solution?
The boiling point of a solution can be determined by measuring the temperature at which the solution changes from a liquid to a gas. This temperature is typically higher than the boiling point of the pure solvent due to the presence of solute particles in the solution.
Why does the pink color at the first equivalence point fade only gradually?
The pink color at the first equivalence point in a titration involving phenolphthalein fades gradually because the solution is in a buffer region. At the equivalence point, there is a mix of weak acid and its conjugate base, which causes the pink color to fade slowly as the pH changes only slightly during the titration.
