Neutralization Reactions

Postby Letty Liu 2C » Sun Dec 01, 2019 11:02 am

For problems like "Select an acid and a base for a neutralization reaction that results in the formation of (a) potassium bromide; (b) zinc nitrite; (c) calcium cyanide, Ca(CN)2; (d) potassium phosphate. Write the balanced equation for each reaction." How do we know which atoms are paired together? What is the thought process to writing these?

When selecting the acid and base, my thought process would be to add H to the anion and OH to the cation. The compound with the H would be your acid and the compound with OH would be your base. In a neutralization reaction, the H and OH would form H2O and the remaining anion and cation would form the compound you were seeking to be the product.

To balance the equations we look at the charges of each ion and use multiples of those ions to make their charges cancel each other out.

For example, since calcium has a (+2) charge and the anion has a (-3) charge, we have 3 Ca and 2 of the anion.
