2B - Acids, bases & salts definitions

Question 1

Acid (2x definitions)

Answer 1

• Substance that releases H⁺ ions in aqueous solution
• Proton donor

Question 2

Strong acid / Weak acid

Answer 2

Strong acid = fully dissociates in solution

Weak acid = Partially dissociates in solution

Question 3

Bases / Alkalis

Answer 3

Bases = Proton acceptors

Alkalis = A soluble base that releases OH^- ions in water. Or a proton acceptor

Question 4

Salt

Answer 4

Salts are ionic compounds formed when the H⁺ ions in acids are replaced by metal ions or ammonium ions

Question 5

Spectator ion

Answer 5

Ions that don’t undergo any change.

They’re still in solution
