Question

What are the properties of acids?

• A. It produces the hydroxyl ion $\left(O{H}^{-}\right)$
• B. It produces the hydronium ion $\left(H_3{O}^{+}\right)$ in aqueous solution
• C. They are proton donors
• D. They have low pH

Answer 1

Answer: (B), (C), (D)

The correct options are
B It produces the hydronium ion $\left(H_3{O}^{+}\right)$ in aqueous solution
C They have low pH
D They are proton donors

Acids have the following properties:

• They produce the hydroxyl ions $H_{3}O+$
• are proton donors as they give $H^{+}$
• have a low $pH$ as the $H^{+}$ concentration is high, and pH being negative of log of $H^{+}$ concentration.
