Statement -1 :An original solution containing excess of `Ni^(2+)` ions gives a yellow coloured solution with potassium cyanide solution.
Statement-2 :A solution of `Ni^(2+)` ions gives red precipitate with dimethylglyoxime solution just made alkaline with ammonia.

Options

A. STATEMENT-1 is true, STATEMENT-2 is true and STATEMENT-2 is correct explanation for STATEMENT-1
B. STATEMENT-1 is true, STATEMENT-2 is true and STATEMENT-2 is not correct explanation for STATEMENT-2
C. STATEMENT-1 is true, STATEMENT-2 is false
D. STATEMENT-1 is false, STATEMENT-2 is true

Answer

To analyze the statements provided in the question, we will evaluate each statement step by step.

### Step 1: Evaluate Statement 1
- **Statement 1**: An original solution containing excess of `Ni^(2+)` ions gives a yellow coloured solution with potassium cyanide solution.
- **Analysis**: When `Ni^(2+)` ions react with cyanide ions (`CN^-`) from potassium cyanide, they form a complex ion, specifically `Ni(CN)₄^(2-)`. This complex is known to exhibit a yellow color.
- **Conclusion**: Statement 1 is **True**.

### Step 2: Evaluate Statement 2
- **Statement 2**: A solution of `Ni^(2+)` ions gives a red precipitate with dimethylglyoxime solution just made alkaline with ammonia.
- **Analysis**: When `Ni^(2+)` ions react with dimethylglyoxime in an alkaline medium (provided by ammonia), they form a red precipitate of nickel dimethylglyoxime complex. This is a well-known qualitative test for nickel ions.
- **Conclusion**: Statement 2 is **True**.

### Step 3: Determine the Relationship Between the Statements
- **Relationship Analysis**: While both statements are true, Statement 2 does not provide a reason for Statement 1. Statement 1 discusses the formation of a yellow solution with potassium cyanide, while Statement 2 discusses the formation of a red precipitate with dimethylglyoxime. The two reactions are independent of each other.
- **Final Conclusion**: Statement 1 is true, Statement 2 is true, but Statement 2 is not a correct explanation for Statement 1.

### Final Answer
- Statement 1 is true.
- Statement 2 is true.
- Statement 2 is not a correct explanation for Statement 1.

The correct answer is **B**.
