What colo is PHTH in Sodium Hydroxide?
Phenolphthalein turns pink in basic solutions
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 two clear liquids mixed make a colored liquid?
When you mix a clear solution of sodium hydroxide (NaOH) with a clear solution of phenolphthalein, the result is a colored liquid. Sodium hydroxide is a strong base, and phenolphthalein is a pH indicator that turns pink in basic conditions. When combined, the phenolphthalein changes color, resulting in a vibrant pink solution. This is a common demonstration in chemistry to illustrate acid-base indicators.
What is the color when caustic soda reacts with phenolphthalein?
When caustic soda (sodium hydroxide) reacts with phenolphthalein, the solution turns pink or magenta in color. This color change indicates that the solution has become basic or alkaline.
What colour is made by mixing methyl orange and sodium hydroxide?
The color is yellow.
What colo is PHTH in Sodium Hydroxide?

Colors of sodium hydroxide in phenolphthalein?
Sodium hydroxide in phenolphthalein solution appears as a bright pink color when the solution is basic due to the presence of hydroxide ions. Conversely, in neutral or acidic solutions, the color fades to become colorless.
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.
What colour would a mixture thymol blue and phenolphthalein go if sodium hydroxide was added?
The mixture would turn from yellow to blue as the pH increases with the addition of sodium hydroxide. Thymol blue changes color from yellow to blue in basic solutions, while phenolphthalein remains colorless 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 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.
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.
