    Remember the Solubility Rules:

    1. All nitrates and acetates are soluble. 

    2. All Group I and Ammonium salts are soluble.

    If you look at the rules for predicting solubility of ionic compounds, a common feature is that salts of NO3- and Group 1 metal ions (K+, Na+...) are always soluble.
