The color of phenolphtalein in basic medium is "fuchsia".
Aniline doesn't react with sodium hydroxide.
The salt formed when sodium hydroxide is added to nitric acid is sodium nitrate (NaNO3).
No. Sodium hydroxide releases hydroxide ions, which actually take protons out of the solution. This qualifies sodium hydroxide as a base.
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.
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, 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.
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.
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.
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.
A base - sodium hydroxide.
