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 does phenolphthalein do when mixed with salts?
The Phenophtalein will remain clear.
Does sodium carbonate react with phenolphthalein indicator?
Sodium carbonate does react with phenolphthalein indicator, producing a color change from colorless to pink in alkaline solutions. Sodium carbonate is a common base that can be used to test for the presence of acidity or alkalinity in a solution using phenolphthalein.
Why is phenolphthalein not suitable for titration involving carbonate?
Phenolphthalein is not suitable for titrations involving carbonates because it is not sensitive enough to detect the pH endpoint when carbonates are involved. Carbonates react with the strong acid used in the titration, forming bicarbonates, which further react to release carbon dioxide, making it challenging to accurately determine the endpoint using phenolphthalein.
Why phenolphthalein get colour on basic medium?
Phenolphthalein is colorless in acidic solutions but turns pink or purple in basic solutions because the hydroxide ions in the basic medium react with phenolphthalein to form a pink-colored compound. This color change is due to a shift in the chemical structure of phenolphthalein when exposed to a basic environment.

What has the author Michael A Becerra written?

Does metal react with bases to produce salts?
Yes, metals can react with bases to form salts through a process called neutralization. The metal hydroxide and the base react to form a salt and water. The salt formed will depend on the specific metal and base involved in the reaction.
Do bases react vigorously with many metals?
No, Acids react with metals to form salts.
What is the reaction of hydrochloric acid and phenolphthalein?
Hydrochloric acid (HCl) is a strong acid that will react with phenolphthalein, a pH indicator, causing it to turn colorless in acidic conditions. This reaction occurs due to the change in pH of the solution, which shifts the equilibrium of the phenolphthalein molecule leading to its color change.
Difference between phenolphthalein alkalinity and and total alkalinity?
Phenolphthalein alkalinity measures the hydroxide ion concentration in water, specifically the amount that can be neutralized by strong acids. Total alkalinity, however, measures the water's ability to neutralize acids, including carbonate, bicarbonate, and hydroxide ions. In summary, phenolphthalein alkalinity focuses on the hydroxide ions, while total alkalinity considers a broader range of alkaline substances.
What products are formed when bases react with an acid?
salts
