TRUE OR FALSE

1. The hydrogen ion and the hydronium ion can be used interchangeably in a chemical equation to represent a hydrogen ion in aqueous solutions.

2. The Bronsted-Lowry model says that an acid is a hydrogen-ion acceptor.

3. The pH scale go from 1 to 15

4. An acidic solution contains more hydrogen ions than hydroxide ions.

5. NaOH is a base

6. Acids and bases are good conductors.

7. Lemon soda has a low pH, therefore is classified as a base.

8. The Arrhenius model states that an acid is a substance that contains hydrogen ions and ionizes to produce hydrogen ions in aqueous solution.

9. Acids taste bitter.

10. In the self-ionization of water, hydronium and hydroxide are the two ions produced.

11. A substance with a pH of 3 is an acid.

12. If you add the pH to the pOH the answer is 14.

13. HCl is hydrochloride acid.

14. The pOH is higher than 8 for acids.

1. True

2. False

3. False

4. True

5. True

6. True

7. False

8. True

9. False

10. True

11. True

12. True

13. True

14. True

15. True

16. False

17. True

Explanation:

1. True

The H⁺ ion is essentially a proton and is transferred to other H₂O molecule to form the hydronium (H₃O⁺) ion, hence, they can be used interchangeably in aqueous solutions.

2. False

A Br∅nsted-Lowry acid is a hydrogen ion or proton donor

3.  False

The pH scale go from 1 to 14

4. True

Due to the shift in the balance in the hydrogen ions concentration when an acid is dissolved in a solution, an acid contains more hydrogen ions than hydroxide ions in the solution

5. True

In an aqueous solution, NaOH dissociates to form Na⁺ and OH⁻ making it a base

6. True

Water soluble acids and bases dissociates into ions in aqueous solution and can conduct electricity

7. False

A base is a substance with a high pH

8. True

Arrhenius model of an acid states that an acid contains and ionizes to produce hydrogen ions

9. False

Due to the hydrogen ion, acids tastes sour

10. True

The reaction for the self ionization of water is as follows;

2H₂O (l) ⇄ H₃O⁺ (aq) + OH⁻ (aq)

11. True

Acids are substances with pH below 7

12. True

The sum of pH and pOH is 14

13. True

In an aqueous solution, HCl dissociates to produce hydronium (H₃O⁺) ion

14. True

pH = 14 - pOH, therefore, for a substance to have a pH below 7 (acidic), the pOH should be higher than 8

15. True

Sodium hydroxide reacts with water and zinc to produce hydrogen gas and sodium zincate

16. False

Monoprotic donate one hydrogen ion

17. True

The pH is found by taking the negative logarithm of the hydrogen ion concentration.

fun caring loving person

c. orbital shape i hope this is correct
