Phenolphthalein, a pH indicator, is colorless in acidic solutions and turns pink in basic solutions due to a change in its molecular structure. In an acid, the phenolphthalein molecule retains its colorless form as it undergoes a chemical reaction with the acidic environment.

What indicators can be used in titration?

Acid Alkali Indicator Details Strong Strong Methyl Orange pipette alkali, and burette acid (change from yellow to light pink when neutralised) Weak Strong Phenolphthalien pipette acid, and burette alkali (change from colouless to salmon pink when neutralised) Strong Weak Methyl Orange pipette alkali, and burette acid (change from yellow to light pink when neutralised) Acid Alkali Indicator Details Strong Strong Methyl Orange pipette alkali, and burette acid (change from yellow to light pink when neutralised) Weak Strong Phenolphthalien pipette acid, and burette alkali (change from colouless to salmon pink when neutralised) Strong Weak Methyl Orange pipette alkali, and burette acid (change from yellow to light pink when neutralised)


What happens if you put gold into sulfuric acid?

Nothing happens. Gold will not react with sulfuric acid.


What happens when a fatty acid is reacted with NaOH?

When a fatty acid is reacted with NaOH, a process called saponification occurs. This reaction results in the formation of soap, which is a salt of the fatty acid alongside glycerol. This reaction is commonly used in soap-making processes.


What happens when you add sulfuric acid to water?

When sulfuric acid is added to water, it dissociates into hydrogen ions and sulfate ions. This process releases heat, so it is important to add the acid to water slowly and with stirring to prevent splashing or overheating. Additionally, diluting sulfuric acid with water helps to reduce the acidity and make it safer to handle.
