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.
Can I lower the pH of sodium hydroxide with water?
No, adding water to sodium hydroxide will not lower the pH. Sodium hydroxide is a strong base, and when dissolved in water, it dissociates to produce hydroxide ions, which make the solution more basic. To lower the pH of a sodium hydroxide solution, you would need to add an acid to neutralize the base.
How do you make a 5 percent water solution of sodium hydroxide?
To make a 5% water solution of sodium hydroxide, you would mix 5 grams of sodium hydroxide with 95 grams of water. This will give you a total of 100 grams of solution, with 5% of it being sodium hydroxide. Remember to always add the sodium hydroxide to the water slowly and with caution due to its caustic nature.
What is the viscosity of 25 sodium hydroxide?
The viscosity of a 25% sodium hydroxide solution would be dependent on temperature. At room temperature (around 25°C), the viscosity of 25% sodium hydroxide solution is approximately 15-20 cP (centipoise).
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.

Would the pH of a sodium hydroxide solution be above or below 7?
NaOH is a base so it will produce a pH above 7.
What is pH of 50 percent solution of sodium hydroxide solution and water?
The pH of a 50% solution of sodium hydroxide (NaOH) and water would be around 13. Sodium hydroxide is a strong base, so when dissolved in water it will result in a highly alkaline solution with a high pH value.
Is copper soluble in sodium hydroxide?
Metallic copper does not react with sodium hydroxide. But if sodium hydroxide is added into a solution of copper ions, it would form Copper(II) Hydroxide. It is a precipitate which is insoluble in water.
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.
What would require the largest volume of 0.100M sodium hydroxide solution for neutralization?
The largest volume of 0.100M sodium hydroxide solution would be needed to neutralize a strong acid with a low molarity. This is because a lower molarity acid would require more moles of sodium hydroxide to neutralize it, resulting in a higher volume of the solution being needed.
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 volume in mLs of 0.100 M sodium hydroxide solution must be added to 20.0 mL of 0.08 M sulfuric acid solution to reach the end point?
To neutralize the sulfuric acid completely, you need a 1:2 molar ratio of sodium hydroxide to sulfuric acid. Therefore, you would need to add twice the amount of sodium hydroxide compared to the amount of sulfuric acid, which is 40.0 mL of the sodium hydroxide solution.
What is the pH of 10 mol per liter of sodium hydroxide solution?
The pH of a 10 M sodium hydroxide solution would be around 14, as sodium hydroxide is a strong base that dissociates completely in water to yield hydroxide ions, which are responsible for the high pH.
