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.
Is sodium hydroxide solution neutral?
No, sodium hydroxide solution is not neutral. It is a strong base with a pH greater than 7.
What is the molarity of a 3 sodium hydroxide solution?
A 3 M sodium hydroxide solution means there are 3 moles of sodium hydroxide dissolved in 1 liter of solution.
How many pounds of Sodium Hydroxide does it take to make 10 gallons of 50 percent Sodium Hydroxide solution?
To make 10 gallons of a 50% sodium hydroxide solution, you would need 10 pounds of sodium hydroxide. This is because the percentage indicates the weight of sodium hydroxide in the solution. Hence, in a 50% solution, half of the weight of the solution is sodium hydroxide.
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.
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.
Is sodium hydroxide unknown solution?
Sodium hydroxide is not an unknown solution.
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 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 molarity of a 3 sodium hydroxide solution?
A 3 M sodium hydroxide solution means there are 3 moles of sodium hydroxide dissolved in 1 liter of solution.
Is sodium hydroxide solution neutral?
No, sodium hydroxide solution is not neutral. It is a strong base with a pH greater than 7.
What happens when methyl orange is added to sodium hydroxide?
When methyl orange is added to sodium hydroxide, the color of the solution changes from red (acidic) to yellow (basic). This indicates that the solution has become more alkaline due to the reaction between the sodium hydroxide and the indicator. Methyl orange is an acid-base indicator that changes color based on the pH of the solution.
What is the pH colour of sodium hydroxide?
Sodium hydroxide is a colourless liquid, and it is also called as caustic soda.
How many pounds of Sodium Hydroxide does it take to make 10 gallons of 50 percent Sodium Hydroxide solution?
To make 10 gallons of a 50% sodium hydroxide solution, you would need 10 pounds of sodium hydroxide. This is because the percentage indicates the weight of sodium hydroxide in the solution. Hence, in a 50% solution, half of the weight of the solution is sodium hydroxide.
Why does sodium hydroxide turn universal indicator blue?
When sodium hydroxide is added to universal indicator solution, it causes the indicator to turn blue because sodium hydroxide is a strong base. The blue color represents a high pH level, indicating that the solution has become more alkaline due to the presence of hydroxide ions released by the sodium hydroxide.
