Acid + Base = _________ + _________

Acid + Base = salt + water_

Acid + Base is a ____________________ reaction.

Acid + Base is a neutralization reaction.

Neutralization reactions: 1. circle the acid 2. box the base 3 Neutralization reactions: 1. circle the acid 2. box the base 3. underline the salt 2HBr + Mg(OH)2 → MgBr2 + 2 H2O HCl + NaOH → NaCl + H2O

Neutralization reactions: 1. circle the acid - start with H 2 Neutralization reactions: 1. circle the acid - start with H 2. box the base - end with OH 3. underline the salt - product 2HBr + Mg(OH)2 → MgBr2 + 2 H2O HCl + NaOH → NaCl + H2O
