What is the colour of the universal indicator in the acid?
The universal indicator turns red in acidic solutions.
Indicator that turns red in acid and blue in alkali?
Litmus paper is a common indicator that turns red in acidic solutions and blue in alkaline solutions.
Universal indicator is a solution that changes what in an acidic or alkali solution?
Universal indicator changes color in acidic or alkaline solutions due to variations in hydrogen ion concentration. In acidic solutions, it turns red/orange, and in alkaline solutions, it changes to blue/purple.

Which indicator gives us reddish pink color in acidic solution?
The red or pink color in an acidic solution is typically due to the presence of an acid-base indicator called phenolphthalein. In acidic conditions, phenolphthalein turns colorless, while in basic conditions it turns red or pink.
What is the colour of methyl red when added to an acid?
Methyl red is red in acidic solutions, as it changes color from red to yellow at a pH around 4.4. This makes it a common indicator to distinguish between acidic and basic solutions.
What is a indicator of acid and alkali?
One common indicator of acids and bases is litmus paper. Litmus paper turns red in acidic solutions and blue in basic solutions. Another indicator is phenolphthalein, which is colorless in acidic solutions and pink in basic solutions.
What is a indicator of acid?
All acidic solutions are colourless in phenolphthalein, pink in methyl orange solution and turns blue litmus paper into red.
