- **Adding Copper Sulphate to Food Item**
Copper sulphate, when added to a food item, will cause a color change depending on the pH level of the food item. Here is how the color change may occur:
- **Blue Color**:
If the food item is acidic, the copper sulphate will react with the acid and form a blue-colored complex. This blue color is a characteristic of copper compounds in acidic solutions.
- **Green Color**:
In neutral pH conditions, the color may appear green. This is due to the formation of a different copper complex in the food item.
- **No Color Change**:
If the food item is basic, there might be no significant color change observed. The copper sulphate may not react effectively in basic conditions.
It is important to note that adding copper sulphate to food items is not recommended due to its potential toxicity. Copper sulphate is a chemical compound that can be harmful if ingested in large quantities. It is primarily used in agriculture and industry, not in food preparation.
