Why are different products obtained when molten and aqueous NaCl are electrolized?
When molten NaCl
is electrolyzed, the two elements sodium and chlorine are produced at the cathode and anode respectively. In an aqueous solution, however, hydrogen gas is produced at the cathode and oxygen gas at the anode, because these reactions can occur at lower electrode potentials than the production of the elements of NaCl.

Which three products are formed by electrolysis of aqueous cesium bromide?
1) Caesium hydroxide2) Bromine NOT Bromide !!3) Hydrogen
When aqueous calcium nitrate is added to aqueous lithium sulfate a reaction occurs?
When aqueous calcium nitrate is added to aqueous lithium sulfate, a double displacement reaction occurs. The calcium and lithium ions switch places to form calcium sulfate and lithium nitrate. This reaction results in the formation of two new compounds: CaSO4 and LiNO3.
What reaction happens between aqueous chlorine and sodium bromide solution?
The reaction between aqueous chlorine and sodium bromide solution results in the displacement of bromine by chlorine, forming sodium chloride and bromine gas as products. This is a redox reaction where chlorine is reduced and bromine is oxidized.
What is the molecular formula if Aqueous hypochlorous acid and aqueous calcium hydroxide react?
The reaction of aqueous hypochlorous acid (HOCl) and aqueous calcium hydroxide (Ca(OH)2) would produce calcium hypochlorite (Ca(OCl)2) as one of the products. So, the molecular formula for this reaction would be 2HOCl + Ca(OH)2 -> Ca(OCl)2 + 2H2O.
When an aqueous solution of lithium chloride is mixed with an aqueous solution of ammonium sulfate what happens?
A chemical reaction occurs where lithium sulfate and ammonium chloride are formed. These products are both soluble in water and remain in solution. The reaction is: LiCl + (NH4)2SO4 → Li2SO4 + 2NH4Cl.
How can you make salts out of aqueous ammonia?
Salts are obtained after the reaction of NH4OH with acids.
What would happen if an aqueous solution of sugar is heated to dryness?
Crystals of sugar are obtained.
Will there be a reaction if all reactants and possible products are aqueous?
Yes, between reactive chemicals there is likely to be a reaction which will lead to precipitation if all the reactants and possible products are aqueous. The reactants, although aqueous, could fail to react if they are endothermic.
How is an aqueous solution different from other solutions?
In an aqueous solution the solvent is water.
Will there be a reaction if all reactants and possible products are aqueous while no insoluble salts precipitate are formed?
There will be no reaction if all the reactants and possible products are aqueous while there is no insoluble salts precipitate that are formed.
What is electrolysis of aqueous sodium chloride?
Sodium metal can be obtained by electrolysis from molten mixture of sodium chloride and calcium chloride in Down's cell. The metal can not be obtained by electrolysis from aqueous solution, because hydrogen will evolve instead.
What is a different word for a chemical liquid?
aqueous
When aqueous H2SO4 and aqueous Na OH react by double replacement?
When aqueous H2SO4 and aqueous NaOH react by double replacement, they form water (H2O) and sodium sulfate (Na2SO4) as products. The reaction is H2SO4 + 2NaOH → 2H2O + Na2SO4.
How is aqueous solution different from other solutions.?
In an aqueous solution the solvent is water.
What are the products of the double-replacement reaction between aqueous hydrogen bromide and aqueous sodium hydroxide?
The products of the double-replacement reaction between aqueous hydrogen bromide and aqueous sodium hydroxide are water and sodium bromide. The hydrogen ion from HBr combines with the hydroxide ion from NaOH to form water, while the sodium ion from NaOH combines with the bromide ion from HBr to form sodium bromide.
What is the chemical equation for aqueous strontium sulfide and aqueous copper sulfate?
The chemical equation for the reaction between aqueous strontium sulfide (SrS) and aqueous copper sulfate (CuSO4) is: SrS + CuSO4 → SrSO4 + CuS Strontium sulfate (SrSO4) and copper sulfide (CuS) are the products of this double displacement reaction.
What is the formula for Aqueous nitric acid and aqueous ammonia react?
The reaction between aqueous nitric acid (HNO3) and aqueous ammonia (NH3) produces ammonium nitrate (NH4NO3) and water (H2O) as products. The balanced chemical equation for this reaction is: HNO3 + NH3 → NH4NO3 + H2O.
