Often, right after titrant is added, the drop turns dark pink then disappears after swirling. Is the following explanation for this phenomenon true or false? The localized concentration of base from the droplet is higher than the rest of the solution. This causes the indicator to turn pink in that area. After swirling the base disperses and the concentration is constant for the entire solution in the flask, causing the color to change back from pink to colorless. True False

Transcribed Image Text:Often, right after titrant is added, the drop turns dark pink then disappears after swirling. Is the following
explanation for this phenomenon true or false?
The localized concentration of base from the droplet is higher than the rest of the solution. This causes the
indicator to turn pink in that area. After swirling the base disperses and the concentration is constant for the
entire solution in the flask, causing the color to change back from pink to colorless.
