How do you prepare phenolphthalein indicator for titration?

Answer 1

Add about 1g solid in 100 mls. ethanol shake well and filter the solution.

Answer 2

Upon swallowing such a solution, you would collapse almost immediately and lose consciousness within 10-20 seconds. Death would follow in a matter of minutes.

With such a massive dose taken, any medical assistance, no matter how aggressive, would prove futile.

A gram mixed in with about 4 to 8 oz water would render you unconscious within 15-45 sec (depending on your body) and without medical attention you would be dead within 30-45 min.

Answer 3

To prepare phenolphthalein indicator for titration, dissolve phenolphthalein powder in ethanol or a 1:1 mixture of ethanol and water to make a concentration of around 1% w/v. This solution can then be added dropwise to the titration flask to detect the endpoint of the titration based on the color change.
