When sodium hydroxide is added to milk, it causes the casein proteins in milk to denature and unfold. These denatured proteins interact with each other and with other milk components to form a network, creating a film on the surface of the milk. This film is often referred to as a milk skin or milk scum.

What happens when sodium is added to water and universal indicator?
When sodium is added to water, it reacts vigorously, releasing hydrogen gas and forming sodium hydroxide. The solution will become alkaline due to the formation of sodium hydroxide. When universal indicator is added, it will change color to indicate a high pH level, typically turning purple or blue for strong alkaline solutions.
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 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 will happen if a small amount of sodium hydroxide is added to a 0.1 M solution of ammonia?
The sodium hydroxide will react with ammonia to form a complex called sodamide and water. This reaction will increase the pH of the solution and result in the formation of a new compound.
What is the colour change when sodium hydroxide is added to iron II sulphate?
When sodium hydroxide is added to iron(II) sulfate, a green precipitate of iron(II) hydroxide is formed.
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.
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.
What happens when sodium hydroxide is added to acetic acid?
When sodium hydroxide is added to acetic acid, a neutralization reaction occurs, resulting in the formation of sodium acetate and water. This reaction also releases heat. Additionally, the resulting solution will be basic due to the presence of excess hydroxide ions.
What happens when sodium hydroxide is added to ferrous chloride?
When sodium hydroxide is added to ferrous chloride, a precipitation reaction occurs. This results in the formation of insoluble ferrous hydroxide, which appears as a greenish precipitate. The balanced equation for this reaction is: FeCl2 + 2NaOH → Fe(OH)2 + 2NaCl.
What alkali could be added to a strong acid to neutralise it?
A common alkali that can be added to a strong acid to neutralize it is sodium hydroxide (NaOH) or commonly known as caustic soda. When sodium hydroxide is added to a strong acid, such as hydrochloric acid, a neutralization reaction occurs, resulting in the formation of water and a salt.
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).
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 happens if you added soduim hydroxide solution to some hydrochloric acid in a beaker?
When sodium hydroxide solution is added to hydrochloric acid in a beaker, a chemical reaction occurs, resulting in the formation of water and sodium chloride salt. This reaction is exothermic, meaning it releases heat energy. The pH of the resulting solution will increase due to the presence of sodium hydroxide, which is a strong base.
What happens when you mix water and sodium?
When water is added to sodium, a violent chemical reaction occurs, resulting in the release of hydrogen gas and the formation of sodium hydroxide. The reaction is highly exothermic and can be dangerous due to the potential for explosion.
What happens if you mix distilled water and sodium hydroxide?
When you mix distilled water with sodium hydroxide, the sodium hydroxide will dissolve in the water, releasing hydroxide ions. This will result in the formation of a basic solution due to the presence of hydroxide ions, which can cause the solution to become caustic and potentially harmful if not handled properly.
What happens when you add sodium hydroxide to copper bromide?
When sodium hydroxide is added to copper bromide, a precipitation reaction occurs, leading to the formation of solid copper hydroxide and sodium bromide in solution. The copper hydroxide is insoluble in water and will appear as a precipitate.
What happens when sodium is added to water and universal indicator?
When sodium is added to water, it reacts vigorously, releasing hydrogen gas and forming sodium hydroxide. The solution will become alkaline due to the formation of sodium hydroxide. When universal indicator is added, it will change color to indicate a high pH level, typically turning purple or blue for strong alkaline solutions.
