Question

A student analyzes a mixture containing KClO₃ using the procedure outlined in this experiment. Which of the following is the correct chemical formula for potassium chlorate?

a) KClO₃
b) KCl₂O
c) K2ClO₃
d) KCl₃O

Answer 1

The correct chemical formula for potassium chlorate is KClO₃ (option a).

Step-by-step explanation:

The correct chemical formula for potassium chlorate is KClO₃ (option a). It consists of one potassium ion (K⁺), one chloride ion (Cl⁻), and three oxygen ions (O²⁻) in the ratio of 1:1:3. The formula is derived from the charges of the ions and the principle of charge balance in compounds.
