Why phenol red is used in titration of strong acid and strong base?
Phenol red is used as an indicator in titrations of strong acids and strong bases because it undergoes a color change in a specific pH range suitable for these titrations. It changes from red (in acidic conditions) to yellow (in basic conditions) around pH 8.2-10, making it ideal for detecting the endpoint of the titration between a strong acid and a strong base.
What color is phenol red as a base?
Phenol red is red in its basic form.
What does is mean when phenol red turns yellow in a experiment?
phenol red turns yellow because it reacts to carbonic acid, which is a product of carbon dioxide mixing with H2O, or water. Phenol red is a Ph indicator, but not a very good one, so it reacts to strong acids (yellow orange) and strong bases (pink) hope this helped!
What is an indicator used to detect an acid or base?
An indicator used to detect an acid or base is a substance that changes color in the presence of acids or bases. Examples of indicators include litmus paper, phenolphthalein, and universal indicator solution.
Which phrase is not true about strong acids?
"Strong acids are weak electrolytes" is not true about strong acids. Strong acids completely dissociate in water to form ions, resulting in strong electrical conductivity.

What color is phenol red as a base?
Phenol red is red in its basic form.
What reaction do you get when you mix phenol red with acids and bases?
Phenol red is yellow under pH=6,8 and pink over a pH=8,2.
What color is phenol red at an base pH?
green

What does phenol red smell like?
Phenol red itself does not have a strong odor. However, if contaminated or in specific conditions, it may emit a slightly sweet or medicinal smell.
What colour will phenol turn litmus paper?
Phenol is a weak acid, so it can turn blue litmus paper red, indicating its acidic nature. However, phenol does not significantly affect red litmus paper, as it is not a strong enough acid to change its color. Overall, phenol primarily affects blue litmus paper by turning it red.
Baking Soda mixed with calcium chloride and phenol red solution chemicla or physical change?
It is a chemical change because it produces heat which is evidence that a chemical change has occured.

What color is phenol red at a neutral?
Phenol red is made by condensation of Phenol and saccharine.pH below 6.8 = YellowpH above 8.2 = Red/FuschiaGradually turns from yellow to red/fuschia (pH between 6.8 and 8.2 = Pinkish)
Does phenol red change baking soda to red?
Phenol red is a pH indicator that changes color in response to pH changes. It turns yellow in acidic conditions and red in basic conditions. When added to a solution containing baking soda (sodium bicarbonate), which is a basic substance, phenol red can turn red.
