7. In comparing hydrochloric acid (pH 1) and sodium hydroxide (pH 13), is one more dangerous than the other? Why or why not?

Hcl is more dangerous than NaoH in equal concentrations

Explanation:

This is because Hydrochloric acid produces toxic fumes which can lead to breathing difficulties while Sodium hydroxide does not produce these fumes easily.

Hcl produces a very burning sensation when it touches the skin while NaOH produces a milder sensation due to it having a soapy feel.
