What else can I help you with?
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 is the colour change when sodium hydroxide is added to iron II sulphate?
dark green (but orange - brown if left standing)
How much sodium hydroxide has to be added to acid to form a neutral solution?
i dunno i think, 1st of all, record the pH of the soln concerned. To my opinion, sodium hydroxide is an alkali, thus, its pH is/should b more than 7. Addition of sodium hydroxide to neutralise a soln should b dne to an acidic soln, that is, pH less than 7. By mixing sodium hydroxide to an acidic soln, the pH wil bcme automatically 7 n thus wil b neutral..
When sodium hydroxide is added to water the reaction is endothermic or exothermic?
The reaction of sodium hydroxide with water is exothermic, meaning it releases heat energy. This is because the process of dissolving sodium hydroxide in water releases energy in the form of heat.
When just enough acid has been added to neutralize the sodium hydroxide what colour will the indicator be?
The indicator will change color to indicate when just enough acid has been added to neutralize the sodium hydroxide. For example, phenolphthalein will turn colorless in an acidic solution, indicating that the base has been neutralized.
How do you neutralize sodium added to water?
Sodium react with water forming a base - sodium hydroxide - and releasing hydrogen. Add an acid for neutralization.
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.
Why is sodium hydroxide is sometimes added to a vial of anesthetic solution?
There are times when bacteria, acidify an infected site, therefore adding sodium hydroxide will neutralize the region for a basic site.
Which compound could be added to hydroiodic acid (HI) to neutralize its acidic properties?
A base such as sodium hydroxide (NaOH) can be added to hydroiodic acid (HI) to neutralize its acidic properties and form water and sodium iodide (NaI).
What alkali could be added to a strong acid to neutralise it?
To neutralise a strong acid, you would need a strong alkali (or lots of a weak alkali, but that would be impractical). Potassium hydroxide, sodium hydroxide, lithium hydroxide, calcium hydroxide, calcium hydroxide and magnesium hydroxide would all work.
. 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 the hydrochloric acid would not cause sodium chloride to redissolve. The reaction between hydrochloric acid and sodium hydroxide forms water and sodium chloride, which would remain as a dissolved salt in the solution. The addition of more sodium hydroxide would further neutralize the acid but not reverse the formation of sodium chloride.
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).
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.
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.
