What happens when you mix Sodium hydroxide and phenolphthalein?
When you mix sodium hydroxide and phenolphthalein, you will observe a color change. Phenolphthalein is commonly used as a pH indicator, turning pink in basic solutions (such as sodium hydroxide) and colorless in acidic solutions. This color change is a result of the chemical reaction between the sodium hydroxide and phenolphthalein molecules.
Why phenolphthalein is chosen as the suitable indicator for sodium hydroxide?
Phenolphthalein is chosen as a suitable indicator for sodium hydroxide because its color change occurs in the pH range around 8.2 to 10.0, which is close to the pH range of the equivalence point for the titration of a strong base like sodium hydroxide with a strong acid. This allows for a sharp and easily detectable color change at the endpoint of the titration.
What happens when you mix calcium hydroxide and phenolphthalein?
When you mix calcium hydroxide and phenolphthalein, the solution will turn pink or magenta in color. This color change indicates that the solution is basic, as calcium hydroxide is a strong base. Phenolphthalein is a pH indicator that changes color in the presence of bases.
What is the color produced when you add the phenolphthalien to sodium hydroxide solution?
The color produced when you add phenolphthalein to sodium hydroxide solution is pink or magenta. Phenolphthalein is commonly used as an acid-base indicator, turning pink in basic solutions with a pH greater than 8.
What is the chemical reaction of phenolphthalein and sodium hydroxide?
Phenolphthalein reacts with sodium hydroxide to form a pink color, indicating the presence of a base. The chemical reaction involves the deprotonation of phenolphthalein by hydroxide ions to form an ionized molecule with a pink hue.
What colo is PHTH in Sodium Hydroxide?
Phenolphthalein turns pink in basic solutions

What would happen if you added phenolphthalein to sodium hydroxide?
Phenolphthalein is a pH indicator that turns pink in basic solutions. When added to sodium hydroxide, which is a strong base, the phenolphthalein will turn pink to indicate that the solution is basic.
Why does the indicator goes purple in sodium hydroxide solution?
The purple color in sodium hydroxide solution is an indicator of the presence of phenolphthalein, which turns pink in basic solutions. When phenolphthalein is added to sodium hydroxide solution, it reacts with the hydroxide ions in the solution to form the purple color.
In an ammonia stock with phenolphthalein solution would the sodium hydroxide tend to decrease the color intensity?
Yes, sodium hydroxide would tend to decrease the color intensity of the phenolphthalein solution in an ammonia stock. Sodium hydroxide is a strong base that would react with phenolphthalein, causing it to change color from pink to colorless.
What happen when sodium hydroxide is added drop wise to a solution containing phenolphthalein?
When sodium hydroxide is added dropwise to a solution containing phenolphthalein, the solution will initially remain colorless. Once enough sodium hydroxide has been added to make the solution basic, the color will change from colorless to pink or purple, indicating the presence of hydroxide ions. Phenolphthalein is a pH indicator that changes color in the presence of a base.
What is the action of sodium hydroxide on the colour of phenolphthalein?
Phenolphthalein is pink in basic solutions.Phenolphthalein is used as an indicator in volumetry - acid-base titration.
What is the equation of sodium hydroxide with phenolphthalein with hydrochloric acid?
The equation for the reaction between sodium hydroxide (NaOH) and hydrochloric acid (HCl) using phenolphthalein indicator is: NaOH + HCl → NaCl + H2O Phenolphthalein is a pH indicator that turns pink in basic solutions and colorless in acidic solutions.
Why is phenolphthalein indicator used in the titration of oxalic acid against sodium hydroxide?
Phenolphthalein is used as an indicator in the titration of oxalic acid against sodium hydroxide because it undergoes a color change at the pH region where the reaction between oxalic acid and sodium hydroxide is neutralized. Oxalic acid is a diprotic acid, meaning it requires two equivalents of sodium hydroxide to be fully neutralized. Phenolphthalein changes color at a pH of around 8.2-10, which is ideal for indicating the endpoint of the titration.
Why phenolphthalein is chosen as the suitable indicator for sodium hydroxide?
Phenolphthalein is chosen as a suitable indicator for sodium hydroxide because its color change occurs in the pH range around 8.2 to 10.0, which is close to the pH range of the equivalence point for the titration of a strong base like sodium hydroxide with a strong acid. This allows for a sharp and easily detectable color change at the endpoint of the titration.

When you mix calcium hydroxide and phenolphthalein, the solution will turn pink or magenta in color. This color change indicates that the solution is basic, as calcium hydroxide is a strong base. Phenolphthalein is a pH indicator that changes color in the presence of bases.
What is the color produced when you add the phenolphthalien to sodium hydroxide solution?
The color produced when you add phenolphthalein to sodium hydroxide solution is pink or magenta. Phenolphthalein is commonly used as an acid-base indicator, turning pink in basic solutions with a pH greater than 8.
