AI Generated Solution

The correct Answer is:
To determine whether the statement "Turnbull's blue and Prussian's blue respectively are KFe^(II)[Fe^(III)(CN)_(6)] and KFe^(II)(Fe^(II)(CN)_(6)]" is true or false, we need to analyze the chemical compositions of both Turnbull's blue and Prussian blue. ### Step-by-Step Solution: 1. **Identify the Compounds**: - Turnbull's blue is formed when ferrous ions (Fe²⁺) react with potassium ferricyanide (K₃[Fe(CN)₆]). - Prussian blue is formed when ferric ions (Fe³⁺) react with potassium ferrocyanide (K₄[Fe(CN)₆]). 2. **Write the Chemical Formulas**: - The formula for Turnbull's blue is KFe₂[Fe(CN)₆]. This indicates that it contains one ferrous ion (Fe²⁺) and one ferric ion (Fe³⁺). - The formula for Prussian blue is KFe₃[Fe(CN)₆]. This indicates that it contains three ferrous ions (Fe²⁺) and two ferric ions (Fe³⁺). 3. **Analyze the Given Statement**: - The statement claims that Turnbull's blue is KFe^(II)[Fe^(III)(CN)₆] and Prussian's blue is KFe^(II)(Fe^(II)(CN)₆]. - However, according to our analysis: - Turnbull's blue should be KFe₂[Fe(CN)₆], not KFe^(II)(Fe^(II)(CN)₆]. - Prussian blue should be KFe₃[Fe(CN)₆], which is not correctly represented in the statement. 4. **Conclusion**: - Since the chemical formulas provided in the statement do not accurately reflect the true compositions of Turnbull's blue and Prussian blue, the statement is **False**. ### Final Answer: **False**
