What is a substance which when added to water produces hydroxide ions?
A substance that, when added to water, produces hydroxide ions is called a base. Common examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH). These compounds dissociate in water to release hydroxide ions (OH⁻), increasing the solution's pH and making it alkaline.
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.
When Calcium sulphate add to sodium hydroxide?
When calcium sulfate (CaSO₄) is added to sodium hydroxide (NaOH), a reaction occurs that can lead to the formation of calcium hydroxide (Ca(OH)₂) and sodium sulfate (Na₂SO₄), depending on the concentrations and conditions. The equation for this reaction can be represented as: [ \text{CaSO}_4 + 2 \text{NaOH} \rightarrow \text{Ca(OH)}_2 + \text{Na}_2\text{SO}_4. ] Calcium hydroxide is only slightly soluble in water, so it may precipitate out of the solution. This reaction is commonly observed in various chemical processes, including water treatment and construction.
Produces OH - ions when added to water?
A substance that produces OH- ions when added to water is a base. Bases are substances that increase the concentration of hydroxide ions in a solution. Some common examples of bases include sodium hydroxide (NaOH) and potassium hydroxide (KOH).
NaOH base or acid?
NaOH is a strong base. It dissociates in water to produce hydroxide ions, making the solution basic.
What happens when sulphuric acid reacts with sodium hydroxide?
When sulfuric acid reacts with sodium hydroxide, a neutralization reaction occurs producing water and sodium sulfate as products. The balanced chemical equation for this reaction is: H2SO4 + 2NaOH -> 2H2O + Na2SO4.
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.
How do you write ta word and formula equation in which aqueous solution of sulfuric acid and sodium hydroxide reacts to form aqueous sodium sulphate and water?
H2SO4 + 2NaOH ---> Na2SO4 + 2H20 sulphuric acid + sodium hydroxide ----> sodium sulphate + water
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 word equation for making sodium sulphate and water?
Sodium + Sulphate + Water = Sodium Sulphate + Water
Name the solution formed when sodium is added to water?
sodium hydroxide solution
Which acid and alkali make sodium sulphate?
Sodium sulfate is formed when sulfuric acid (H2SO4) reacts with sodium hydroxide (NaOH). This reaction results in sodium sulfate (Na2SO4) and water (H2O) as the products.
What is formed when sulphuric acid reacts with sodium hydroxide?
When sulfuric acid reacts with sodium hydroxide, sodium sulfate and water are formed. The balanced chemical equation for this reaction is: H2SO4 + 2NaOH → Na2SO4 + 2H2O.
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 happends when sulphuric acid reacts with sodium hydroxide?
When sulfuric acid reacts with sodium hydroxide, a neutralization reaction occurs, forming sodium sulfate and water. The balanced chemical equation for this reaction is H2SO4 + 2NaOH -> Na2SO4 + 2H2O.
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 is the symbol equation for sulphuric acid sodium hydroxide sodium sulphate water?
H2SO4+2NaOH------->Na2SO4+H20
