when are drops of indicator most likely added to the erlenmeyer flask?\nwhen preparing the burette\nwhen filling the pipette with acid\nwhen recording the initial burette volume\nwhen preparing to measure ph change
Answer
Brief Explanations:
In an acid - base titration, indicator is added to the Erlenmeyer flask containing the analyte to detect the endpoint by showing a color change as pH changes. It is added when preparing to measure pH change during the titration process.
Answer:
