Answer

To solve the question regarding the formulas for Chile saltpeter and Indian saltpeter, we will break it down step by step.

### Step 1: Identify Chile Saltpeter
- Chile saltpeter is commonly known as sodium nitrate.
- The chemical formula for sodium nitrate is NaNO3.

### Step 2: Identify Indian Saltpeter
- Indian saltpeter is commonly known as potassium nitrate.
- The chemical formula for potassium nitrate is KNO3.

### Step 3: Summarize the Findings
- Therefore, the formulas for the two types of saltpeter are:
- Chile saltpeter: NaNO3 (sodium nitrate)
- Indian saltpeter: KNO3 (potassium nitrate)

### Final Answer
- The formula for Chile saltpeter is NaNO3, and the formula for Indian saltpeter is KNO3.
