Multiple Choice

Predict the products to this reaction: Ag + NaCl ---->

• No reaction

• AgCl + Na

​Neutralization

​Exception for Double Replacement Reactions

​

​If the reaction is an acid-base neutralization, the reaction will happen even if both are soluble.

​

​How to recognize a neutralization reaction:

​Acids usually begin with H, Bases usually end with OH

​H_ + _OH is probably a neutralization

​Products will be water and a "salt"
