Solubility Rules Pyramid Chart - Chemistry Reference Guide #265184 (License: Personal Use)

This educational diagram presents the standard solubility rules used in general chemistry, structured as a pyramid with three levels. Level 1 includes nitrate (NO₃⁻) and ammonium (NH₄⁺) ions, which are always soluble with no exceptions; Level 2 covers halides (Ag⁺, Hg²⁺, Pb²⁺ exceptions) and sulfate (SO₄²⁻, with Ba²⁺, Pb²⁺, Hg²⁺ exceptions); Level 3 lists ions that generally form insoluble precipitates: CO₃²⁻, OH⁻, and PO₄³⁻. The visual hierarchy helps learners quickly predict precipitation reactions.

Used in chemistry textbooks, lecture slides, and study guides to teach qualitative analysis and predict products of double displacement reactions. Matches user intent for quick reference during homework, lab work, or exam prep.
