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.
How will Phenolphthalein help you test for unknown substances?
phenolphthalein turns pink when basic solution is added to it but remains colorless in case of neutral and acidic solution
What happen when oxalic acid is added to phenolphthalein?

What happen when sodium hydroxide is added drop wise to a solution containing phenolphthalein?
It Turns Pink.
How does the color change when a strong acid is added an alkali to neutralise?

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?
Because Hydrochloric acid is an acid, phenolphthalein would be clear. In bases Phenolphtlalein becomes pink
What colour is phenolphthalein when soda is added?
As soda contains carbon dioxide, it's actually a dilute solution of carbonic acid, hence phenolphthalein remains colourless.
What color does ammonia turn when phenolphthalein is added?
it turns into fushia/purpley colour
