Water is weaker/stronger acid than ethanol.

Explanation

To determine whether water is a weaker or stronger acid than ethanol, we can follow these steps:

### Step 1: Define Acidity
Acidity refers to the ability of a substance to donate protons (H+ ions). The strength of an acid is determined by how readily it donates H+ ions.

### Step 2: Identify the Acids
- Water (H2O) can act as an acid by donating a proton to form hydroxide ions (OH-).
- Ethanol (C2H5OH) can also act as an acid by donating a proton to form ethoxide ions (C2H5O-).
