Write a net equation for the reaction between aqueous solutions of NH4Cl and Na2SO3.
see above.
To write the net equation for the reaction between aqueous solutions of NH4Cl and Na2SO3, you first need to determine the products that are formed when these two compounds react.
NH4Cl is made up of ammonium ions (NH4+) and chloride ions (Cl-), while Na2SO3 consists of sodium ions (Na+) and sulfite ions (SO3^2-).
When these two compounds react, they exchange ions to form new compounds. The ammonium ion combines with the sulfate ion to produce ammonium sulfate (NH4)2SO4, while the sodium ion combines with the chloride ion to form sodium chloride (NaCl).
Therefore, the net equation for this reaction can be written as:
2NH4Cl (aq) + Na2SO3 (aq) → (NH4)2SO4 (aq) + 2NaCl (aq)
To write the net ionic equation for the reaction between NH4Cl (ammonium chloride) and Na2SO3 (sodium sulfite), we first need to identify the soluble compounds and any potential reactions that may occur.
1. Start by breaking down the reactants and products into their respective ions:
NH4Cl (ammonium chloride) dissociates into NH4+ (ammonium ion) and Cl- (chloride ion).
Na2SO3 (sodium sulfite) dissociates into 2 Na+ (sodium ions) and SO3^2- (sulfite ion).
2. Next, determine if any precipitation or gas formation reactions occur:
In this case, no precipitation or gas formation reactions occur. Both ammonium ions (NH4+) and sulfite ions (SO3^2-) are soluble in water, while chloride ions (Cl-) and sodium ions (Na+) are also soluble.
3. Now, write the balanced molecular equation:
NH4Cl (aq) + Na2SO3 (aq) → NH4+ (aq) + Cl- (aq) + 2 Na+ (aq) + SO3^2- (aq)
4. Finally, write the net ionic equation:
To write the net ionic equation, we eliminate the spectator ions (ions that appear on both sides of the equation without undergoing a chemical change). In this case, the spectator ions are Cl- and Na+. The remaining ions are NH4+ and SO3^2-. Therefore, the net ionic equation is:
NH4+ (aq) + SO3^2- (aq) → No reaction
In summary, the net ionic equation for the reaction between NH4Cl and Na2SO3 is: NH4+ (aq) + SO3^2- (aq) → No reaction.
