Questions and Answers
Why would handling strong acids require specialized protective equipment and ventilation?
Why would handling strong acids require specialized protective equipment and ventilation?
- Strong acids react violently with other chemicals, potentially causing explosions if not handled carefully.
- Strong acids are primarily dangerous when ingested, requiring precautions against accidental swallowing.
- Strong acids emit radioactive particles, necessitating shielding and monitoring to prevent radiation exposure.
- The corrosive properties of strong acids can cause severe burns and respiratory damage upon contact or inhalation. (correct)
If you were to dilute a strong acid with water, what would be the most important safety precaution?
If you were to dilute a strong acid with water, what would be the most important safety precaution?
- Add acid to the water slowly while stirring to dissipate heat. (correct)
- Add water to the acid quickly to minimize splashing.
- Mix the acid and water in a sealed container to prevent fumes from escaping.
- Cool both the acid and water in an ice bath before mixing to control the reaction.
How does the concentration of an undissociated weak acid in an aqueous solution compare to that of a strong acid at the same molar concentration?
How does the concentration of an undissociated weak acid in an aqueous solution compare to that of a strong acid at the same molar concentration?
- The weak acid will have a significantly higher concentration of undissociated molecules. (correct)
- The weak acid will have a significantly lower concentration of undissociated molecules.
- The weak acid and strong acid will have approximately the same concentrations of undissociated molecules.
- The concentration of undissociated molecules depends on the specific acid, regardless of its strength.

Study Notes
- Many foods contain acids which have a sharp taste and strong odor.
- Strong acids are corrosive.
- Lemonade and lemons contain citric acid, which is a weak acid.
- Hydrochloric acid (HCl), sulfuric acid (H2SO4), and nitric acid (HNO3) are acids used in laboratories.
- Acids are divided into two groups which are weak acids and strong acids.
- Strong acids are highly corrosive, like hydrochloric, nitric and sulfuric acid.
- There is an X sign on bottle labels that denotes danger of corrosion, with the words "harmful substance".
- Acids generally dissolve in water, creating aqueous solutions, which also have corrosive properties.
- Aqueous solutions of weak acids are less corrosive compared to those of strong acids.
