What happens if phenolphthalein was added to salts?
If phenolphthalein is added to a solution of salts, it will not undergo any specific reaction. Phenolphthalein is used as an indicator in acid-base titrations, where it changes color depending on the pH of the solution. Since salts do not have acidic or basic properties, phenolphthalein will not exhibit any color change.
What happen when oxalic acid is added to phenolphthalein?
Phenolphtalein is colorless in an acidic medium.
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 is the chemical formula for Dextromethorphan HBr?
The chemical formula for Dextromethorphan Hydrobromide (HBr) is C18H25NO·HBr.
What color does ammonia with water turn when phenolphthalien was added?
When ammonia is dissolved in water and phenolphthalein is added, the solution turns pink. This occurs because ammonia is a weak base, and the phenolphthalein indicator changes color in basic conditions. The pink color indicates a pH greater than 8.2, which is typical for ammonia solutions.
What color does NaoH turn when phenolphthalein?
NaOH turns pink when phenolphthalein is added.
What color does ammonia turn when phenolphthalein is added?
Ammonia will turn pink when phenolphthalein is added, indicating that the solution is basic.
What would happen if you added phenolphthalein to sodium hydroxide?
Phenolphthalein is a pH indicator that turns pink in basic solutions. When added to sodium hydroxide, which is a strong base, the phenolphthalein will turn pink to indicate that the solution is basic.
What will be the color of phenolphthalein when added to a solution of hydroxide?
Phenolphthalein will turn pink or magenta in color when added to a basic solution containing hydroxide ions.
What happens when water is added to phenolphthalein?
When water is added to phenolphthalein, the color remains the same, which is colorless. Phenolphthalein is typically used as an indicator in titrations with strong acid and strong base where the color change is triggered by changes in pH, not by the addition of water.
What is the color of lime water when phenolphthalein is added into lime water?
The color is pink with phenolphthalein.
What liquid turns pink when Sodium Bicarbonate is added?
phenolphthalein
Write the expression for Ka for the dissociation of HBr?
Ka = [H+].[Br-] / [HBr] However the value of this expression is very high, because HBr is a STRONG acid, meaning that much more than 99.9% of the HBr molecules in water are protolized (ionized), making [H+] and [Br-] equal to the original (added) HBr amount, and the [HBr]-value nearly zero.
What happens if phenolphthalein solution is added in hydrochloric acid?
If phenolphthalein solution is added to hydrochloric acid, it will remain colorless since the pH of hydrochloric acid is too low for phenolphthalein to change color. Phenolphthalein typically turns pink in a basic solution but does not show a color change in acidic conditions.
What happens if phenolphthalein was added to salts?
If phenolphthalein is added to a solution of salts, it will not undergo any specific reaction. Phenolphthalein is used as an indicator in acid-base titrations, where it changes color depending on the pH of the solution. Since salts do not have acidic or basic properties, phenolphthalein will not exhibit any color change.
What is the balanced equation for ammonium hydroxide added to hydrobromic acid?
The equation is NH4OH + HBr -> NH4Br + H2O.
What happen when phenopthelein is added to acid?
Phenolphthalein is colorless in acidic solutions and will remain colorless when added to an acid. This is because phenolphthalein changes color at a pH of around 8.2 to 10, indicating alkalinity.
