Answer to Question #206035 in General Chemistry for marianna

Question

Determine if a precipitation reaction occurs between aqueous silver nitrate and aqueous calcium chloride. If a precipitation reaction takes place, write a balanced chemical equation, total ionic equation and net ionic equation for the reaction. Identify any spectator ions.

Answer 1

To find the products, you simply combine the two 'inner' and two 'outer' elements together. In this case, the two 'inner' elements are Silver and Chloride, while the two 'outer' elements are Calcium and Nitrate. Keep in mind that during this process, subscripts are ignored during the conversion.

Since Silver has a charge of +, and Chlorine's charge is -, you do not need to make any subscript changes here. However, since Calcium's charge is 2+, while Nitrate's charge is -, you have to balance the net charge to zero, which means adding a 2 subscript for nitrate.
