How would you distinguish between oxalic acid and glucose by one chemical test.

Explanation

To distinguish between oxalic acid and glucose using a chemical test, we can use sodium hydrogen bicarbonate (NaHCO3). Here’s the step-by-step solution:

### Step 1: Understand the Chemical Structure
- **Oxalic Acid**: It is a dicarboxylic acid with the formula C2H2O4, containing two carboxylic acid groups (-COOH).
- **Glucose**: It is a simple sugar (monosaccharide) with the formula C6H12O6, and it does not contain any carboxylic acid groups.

### Step 2: Perform the Test
- Take a small amount of oxalic acid and dissolve it in water.
