1.    Sodium Bicarbonate - Baking Soda

2.    Ketchup

3.    Jam

4.    Soap (A mild base)

5.    Oven Cleaner

6.    Citrus

7.    Drain Cleaner

8.    Toothpaste

9.    Bleach

10. Car batteries

11. Ammonia (Sometime found in hair products or cleaning products)

12. Washing Powder

13. Milk

14. Cement

15. Calcium Hydroxide - Slaked lime

Answer 1

1.  Sodium Bicarbonate - Baking Soda - a base (bicarbonate ion serves as hydrogen acceptor);

2.  Ketchup - an acid (contains vinegar as preservative);

3.  Jam - an acid (contain acids from fruits)

4.  Soap (A mild base) - a base (contains salts of strong bases);

5.  Oven Cleaner - a base (contains sodium hydroxide and OH- ions);

6.  Citrus - an acid (contains organic acids);

7.  Drain Cleaner - a base (contains sodium hydroxide and OH- ions);

8.  Toothpaste - a base (contains basic components);

9.  Bleach - a base (dissociates into sodium and hypochlorite ions);

10. Car batteries - an acid (contains hydrochloric acid);

11. Ammonia (Sometimes found in hair products or cleaning products) - a base (in water, dissociation of ammonia gives OH- ions);

12. Washing Powder - a base (contains basic components);

13. Milk - a weak acid (contains lactic acid);

14. Cement - a base (contain basic salts);

15. Calcium Hydroxide - Slaked lime - a base (contains OH- ions).
