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.
Is sodium hydroxide same as sodium phosphate?
No. Sodium hydroxide is NaOH; it is a strong base often used in drain cleaner. Sodium phosphate is Na3PO4; it is a weak base with a number of applications in cleaning and in food.
What is added to sodium hydroxide that will get sodium sulphate and water?
You would need to add Sulphuric acid to make Sodium Sulphate + Water :)
What happen when 2.5M Na OH was added to aniline?
Aniline doesn't react with sodium hydroxide.
If solid sodium hydroxide were added to neutralize the HCl would this reverse the reaction and cause the sodium chloride to redissolve?
No, adding solid sodium hydroxide to neutralize hydrochloric acid (HCl) would not cause sodium chloride to redissolve. The reaction between sodium hydroxide and hydrochloric acid forms water and sodium chloride, which remains in its dissolved form. The addition of solid sodium hydroxide would simply further neutralize the acid and increase the concentration of the resulting sodium chloride solution.
Does sodium hydroxide release protons when added to water?
No. Sodium hydroxide releases hydroxide ions, which actually take protons out of the solution. This qualifies sodium hydroxide as a base.
What is the name of the salt formed when sodium hydroxide is added to nitric acid?
The salt formed when sodium hydroxide is added to nitric acid is sodium nitrate (NaNO3).
Explain what happens when sodium hydroxide solution is added to ammonium hydroxide?
When sodium hydroxide solution is added to ammonium hydroxide, a double displacement reaction occurs. Ammonium hydroxide is a weak base and sodium hydroxide is a strong base. The reaction produces water, sodium hydroxide, and ammonia gas.
When sodium oxide is added to water sodium hydroxide is produced?
When sodium oxide is added to water, it reacts to form sodium hydroxide as a product. This is because sodium oxide is a basic oxide that reacts with water to produce a strong base, sodium hydroxide, along with the release of heat. This reaction is exothermic and can be used in industries for the production of sodium hydroxide.
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.
What is added to dilute hydrochloric acid to get sodium chloride?
A base - sodium hydroxide.
Name the solution formed when sodium is added to water?
sodium hydroxide solution
Can you use glycerin to dissolve sodium hydroxide?
Yes, glycerin can be used to dissolve sodium hydroxide. When sodium hydroxide is added to glycerin, it will dissolve and form a clear viscous solution. It is important to handle sodium hydroxide carefully as it is a caustic substance.
What is the chemical equation when sodium hydroxide is added to iron II?
The chemical equation when sodium hydroxide is added to iron(II) is: Fe(OH)2 (iron(II) hydroxide) + 2NaOH (sodium hydroxide) -> Fe(OH)2 + 2NaOH.
What is the product of Copper carbonate added to sodium hydroxide?
When copper carbonate is added to sodium hydroxide, a chemical reaction occurs to form copper hydroxide and sodium carbonate. Copper hydroxide is a blue solid precipitate, while sodium carbonate remains as a soluble compound in the solution.
What happens when sodium hydroxide is added to copper oxide the colour of precipitate?
When sodium hydroxide is added to copper oxide, a blue precipitate of copper hydroxide is formed. The color of the precipitate is due to the formation of copper ions in solution.
Will Sodium hydroxide react with copper?
Yes, sodium hydroxide can react with copper to form copper(II) hydroxide. When sodium hydroxide is added to a solution containing copper ions, a blue precipitate of copper(II) hydroxide is formed.
