Phenolphthalein change color when mixed with hydrochloric acid?
Phenolphthalein is a pH indicator that changes color in response to a change in pH. When mixed with hydrochloric acid (a strong acid), phenolphthalein will turn colorless due to the decrease in pH, indicating an acidic solution.
What is the reaction of hydrochloric acid and phenolphthalein?
Hydrochloric acid (HCl) is a strong acid that will react with phenolphthalein, a pH indicator, causing it to turn colorless in acidic conditions. This reaction occurs due to the change in pH of the solution, which shifts the equilibrium of the phenolphthalein molecule leading to its color change.
Which 2 indicators turn the same colour with hydrochloric acid?
Methyl orange and methyl red both shows red color in a HCl solution where pH is lesser than 4.71.
What colour does universal indicator turn in dilute hydrochloric acid?
Universal indicator will turn red or pink in dilute hydrochloric acid.
Which Colour do alkali turn phenolphthalein?
Alkalis turn phenolphthalein pink or magenta.

What happens when you mix HCl and phenolphthalein?
When you mix HCl (hydrochloric acid) and phenolphthalein, the phenolphthalein will turn colorless because the strong acid protonates it, resulting in the loss of its pink color. This change in color indicates the presence of an acidic solution.
What can be added to HCl to turn red?
Adding phenolphthalein indicator to hydrochloric acid (HCl) will turn it red in basic solutions.
What colour does hydrochloric acid turn in red litmus paper?
Hydrochloric acid will keep litmus red - it needs alkali to turn it blue
What colour would litmus paper turn into when dipped into hydrochloric acid?
Depends on the litmus paper. Red litmus will not turn but blue litmus will turn redish pink.
What colour does hydrochloric acid turn litmus?
hydrochloric acid usually has pH 1 which turns litmus Red
Colour of litmus papper in dilute hydrochloric acid?
Litmus paper will turn red in dilute hydrochloric acid, indicating that the solution is acidic.
What colour does blue litmus paper turn when dipped in hydrochloric acid?
Red!
