Answer
### 1. Distillation### 2. Diffusion### 3. Crystallization### 4. Distillation### 5. Filtration
Explanation
## Step1: Identify the appropriate separation technique for each mixture### Analyze the properties of each mixture and match them with the most suitable separation technique from the given list.## Step2: Water from aqueous copper(II) sulphate### Distillation is the most suitable technique as it separates components based on their boiling points. Water can be distilled off from the solution.### **Title**: Distillation for separating water from aqueous copper(II) sulphate## Step3: Helium from a mixture of helium and argon### Diffusion is the most suitable technique because helium, being lighter, diffuses faster than argon.### **Title**: Diffusion for separating helium from a mixture of helium and argon## Step4: Copper(II) sulphate from aqueous copper(II) sulphate### Crystallization is the most suitable technique as it allows the solid copper(II) sulphate to form crystals while leaving the water behind.### **Title**: Crystallization for separating copper(II) sulphate from aqueous copper(II) sulphate## Step5: Ethanol from aqueous ethanol### Distillation is the most suitable technique as it can separate ethanol from water based on their different boiling points.### **Title**: Distillation for separating ethanol from aqueous ethanol## Step6: Barium sulphate from a mixture of water and barium sulphate### Filtration is the most suitable technique as barium sulphate is insoluble in water and can be separated by filtering.### **Title**: Filtration for separating barium sulphate from a mixture of water and barium sulphate#
