Question

6) ZnCl2 → Zn(OH)2 →ZnSO4 K2ZnO2

Answer 1

6) ZnCl2 → Zn(OH)2 → ZnSO4 → K2ZnO2

ZnCl2  + 2NaOH = Zn(OH)2 + 2NaCl

Zn(OH)2 + BaSO4 t° = ZnSO4 + Ba(OH)2

ZnSO4 + 2K = K2SO4 + Zn

Answer 2

The chemical equation you provided seems to depict a series of reactions involving zinc chloride (ZnCl2) leading to the formation of zinc sulfate (ZnSO4) and potassium zincate (K2ZnO2), with an intermediate formation of zinc hydroxide (Zn(OH)2). Let's break down the reactions step by step:

1. ZnCl2 → Zn(OH)2: In this step, zinc chloride reacts with water (H2O) to form zinc hydroxide. The balanced equation for this reaction is: ZnCl2 + 2H2O → Zn(OH)2 + 2HCl

2. Zn(OH)2 → ZnSO4: In the next step, zinc hydroxide reacts with sulfuric acid (H2SO4) to produce zinc sulfate. The balanced equation for this reaction is: Zn(OH)2 + H2SO4 → ZnSO4 + 2H2O

3. ZnSO4 K2ZnO2: The final step involves the reaction between zinc sulfate and potassium hydroxide (KOH) to form potassium zincate. The balanced equation for this reaction is: ZnSO4 + 2KOH → K2ZnO2 + H2SO4

Please note that the reaction conditions, such as concentrations and temperatures, are not specified in your question. These factors can influence the reaction rates and the formation of specific products. Additionally, it's important to handle chemicals safely and follow proper laboratory protocols when conducting experiments involving potentially hazardous substances.
