What happens when Ferrous sulphate reacts with sodium hydroxide?
When ferrous sulfate reacts with sodium hydroxide, a precipitate of ferrous hydroxide is formed. The balanced chemical equation for the reaction is FeSO4 + 2NaOH → Fe(OH)2 + Na2SO4. This reaction is a double displacement reaction where the cations and anions switch partners.
Why is sodium hydroxide suitable for absorbing bromine?
Sodium hydroxide is suitable for absorbing bromine because it can react with bromine to form sodium hypobromite, which is soluble in water. This reaction helps remove bromine gas from the atmosphere. Sodium hydroxide is also a strong base that can neutralize any acidic impurities that may be present along with bromine.
Why CaO is not expected to react with sodium hydroxide?
CaO is a basic oxide that does not react with sodium hydroxide, which is also a base. Both substances have high pH levels and do not have reactive properties that would lead to a chemical reaction between them.
Does Polyethylene Glycol reacts with Sodium Hydroxide solution?
No, polyethylene glycol does not react with sodium hydroxide solution. Polyethylene glycol is a non-reactive polymer that is often used as a solvent, while sodium hydroxide is a strong base used for various chemical reactions. Mixing the two will not result in a chemical reaction.
What is the importance of sodium hydroxide in the preparation of bromoaniline?
Sodium hydroxide is used in the preparation of bromoaniline as a base to deprotonate the aniline compound, making it more reactive towards the brominating reagent. This reaction typically involves a substitution of a hydrogen atom on the aniline molecule with a bromine atom. Sodium hydroxide helps facilitate this reaction by providing the necessary basic conditions for the deprotonation step.
Which gas is given out when sodium hydroxide reacts with a metal?
Hydrogen gas is given off when sodium hydroxide reacts with a metal. This is due to the displacement reaction that occurs where the more reactive metal displaces hydrogen from water molecules in the sodium hydroxide solution.

How does the reaction between magnesium (Mg) and sodium hydroxide (NaOH) occur?
When magnesium reacts with sodium hydroxide, it forms magnesium hydroxide and hydrogen gas. This is a chemical reaction where the magnesium displaces hydrogen from the sodium hydroxide, resulting in the formation of magnesium hydroxide and hydrogen gas as products.
Why CaO is not expected to react with sodium hydroxide?
CaO is a basic oxide that does not react with sodium hydroxide, which is also a base. Both substances have high pH levels and do not have reactive properties that would lead to a chemical reaction between them.
What does sodium reacts with?
Sodium is so reactive it is usually found in compounds. It reacts most violently with water, creating sodium hydroxide.
What is the difference in sodium hydroxide and potassium hydroxide?
The difference is that sodium hydroxide contains the sodium ion (Na+) while potassium hydroxide contains the potassium ion (K+). Sodium and potassium are two different elements, though they have different properties.
Does sodium hydroxide occur naturally?
Sodium hydroxide is not found naturally in its pure form, as it is a man-made chemical compound. It is typically produced through the chemical reaction of sodium carbonate with calcium hydroxide.
Is sodium hydroxide a strong alkali?
Yes, it dissociates completely into lithium and hydroxide ions.
What is more reactive potassium hydroxide or sodium hydroxide?
Well...nothing is so black and white. Some things react differently in different situations. However...it is most likely you'd be using both of these as bases, and as such, KOH - potassium hydroxide - is likely slightly more reactive than NaOH. This is by comparison of their pKa values alone, and many things may factor into reactivity. If anything, they're both very similar in the grand scheme of things.
Is aluminum more reactive with hydrochloric acid or sodium hydroxide?
aluminum will produce tiny bubbles
Sodium hydroxide is very reactive If some of sodium hydroxide solution splatters onto a student's hands during the experiment the student should?
wash it off with a large amount of water
