Atoms of which element are present in ALL of the Bronsted-Lowry Acids in Model 2?

(a)  

How can you tell from Reaction 1 that HCl loses an H⁺ ion rather than a hydrogen atom when the reaction occurs? HINT: Look at the products.

• The H₃O⁺ on the product side gained the H and it has a charge

• The Cl- on the product side gained the H and it has a charge

For each acid-base reaction in Model 2, describe the role of the Bronsted-Lowry ACID in the H⁺ ion (proton) transfer that occurs.

• The acid gives up a hydrogen ion and passes it to the base

• The acid accepts a hydrogen ion from the base
