Which of these ions may be precipitated as sulfides? Assume neutral aqueous solution, pH=7.

Silver (I) ion
Sodium ion
Calcium ion
Lead (II) ion
Manganese (II) ion
Ammonium ion

I think the silver I ion, lead II ion, and manganese ion may be precipitated as sulfides, but I'm not sure.

  1. You need to memorize the solubility tables. Here is a simple table (it won't catch everything but it will catch most).
