Hypochlorous Acid and Related Concepts

The video tutorial explains how to write the formula for hypochlorous acid. It begins by clarifying the difference between 'hypo' and 'hydro' and then outlines the steps to derive the formula. The process involves identifying the hypochlorite ion, using a common ion table, and applying charge balance rules to arrive at the correct formula, HClO. The tutorial concludes with a summary of the steps taken.

What is the key difference between 'hypo' and 'hydro' in chemical nomenclature?

• 'Hypo' is used for acids, while 'hydro' is used for bases.

• 'Hypo' indicates the presence of oxygen, while 'hydro' indicates the absence of oxygen.

• 'Hypo' indicates a lower oxidation state, while 'hydro' indicates a higher oxidation state.

• 'Hypo' and 'hydro' are interchangeable terms.

How do you transform the name 'hypochlorous' to find the related ion?

• Add 'hypo' to the beginning.

• Replace 'ous' with 'ite'.

• Replace 'ous' with 'ate'.

• Remove 'hypo' from the beginning.

What is the formula for the hypochlorite ion?

• ClO3-

• ClO2-

• ClO-

• Cl-

Where can you find the formula for the hypochlorite ion?

• In the solubility chart.

• In the molecular weight table.

• In the common ion table.

• In the periodic table.

What charge does the hypochlorite ion carry?

• Positive

• Variable

• Negative

• Neutral

What is the correct formula for hypochlorous acid?

• HCl

• HClO

• HClO3

• HClO2

Why does the combination of H+ and ClO- result in a neutral compound?

• Because the charges are irrelevant in this case.

• Because the positive and negative charges cancel each other out.

• Because both ions have negative charges.

• Because both ions have positive charges.
