• bases
• acids

According to Bronsted-Lowry, which of the following will "donate" an H⁺ ion?

• Acid

• Base

• Solution

• Water

In the equation below, what is the Bronsted-Lowry acid?

HCl + NH₃ → Cl^- + NH₄⁺

• HCl

• NH₃

• Cl^-

• NH₄⁺

Acids which dissociate almost completely in aqueous solutions are known as:

• Dilute acids

• Strong acids

• Weak acids

• Concentrated acids

What are the weak acids and bases?

• all acids and bases are weak
• if not classified as strong, the acid/base is considered weak
• all acids and bases are strong
• there are more strong acids and bases than there are weak acids/bases
