acids-magenta
bases-green
i think it remains in yellow colour
Universal indicator changes to green when sodium bicarbonate is added.
Universal indicator changes to red/orange when hydrochloric acid is added, indicating that the solution is acidic.
Universal indicator changes to a color in the green/blue range when carbonate acid is added. This indicates a basic or alkaline pH level.
the colour of the indicator will increase
When red cabbage indicator is added to acid solutions, it changes to a reddish-pink color. This change occurs due to the presence of anthocyanins in the cabbage, which react with the hydrogen ions in the acid, resulting in a shift in color. In contrast, in basic solutions, the indicator turns green or blue.
Universal indicator turns red when added to vinegar, indicating that the vinegar is acidic.
A neutral solution added to universal indicator will turn green.
green.
red
The color change at the endpoint of titration is usually due to an indicator that has been added to the solution being titrated. The change in color indicates that the reaction is complete and can help determine the endpoint of the titration.
When universal indicator is added to acetic acid, it typically turns a shade of red, indicating that the solution is acidic. Acetic acid is a weak acid, so the color change may not be as intense as with stronger acids.
