Verified step by step guidance1
Recall that boric acid is a weak acid commonly used in antiseptics and has the chemical formula involving hydrogen (H), boron (B), and oxygen (O).
Understand that the general formula for boric acid is written as \(\mathrm{H_3BO_3}\), which means it contains 3 hydrogen atoms, 1 boron atom, and 3 oxygen atoms.
Compare the given options by counting the number of atoms of each element in their formulas:
- \(\mathrm{H_3BO_4}\) has 3 hydrogens, 1 boron, and 4 oxygens.
- \(\mathrm{H_2BO_3}\) has 2 hydrogens, 1 boron, and 3 oxygens.
- \(\mathrm{H_3BO_3}\) has 3 hydrogens, 1 boron, and 3 oxygens.
Identify that the correct formula for boric acid matches \(\mathrm{H_3BO_3}\) because it fits the known composition of boric acid.
