Solubility Rules Chart
With over 140 compounds listed, this chart shows the solubility trends or patterns for ionic compounds and helps reinforce general rules for determining solubility. The table is arranged with groups of cations listed across the top and anions listed on the side. Match any cation and anion to determine the relative solubility of the corresponding ionic compound.

Two clear solutions are combined to form a homogeneous mixture. As a solid chemical is added, the two seemingly inseparable solutions begin to “sort” into two layers. As more solid is added, the two layers become more distinct. Teacher Demonstration Notes included.

Flinn Digital Magnetic Stirrer/Hot Plates
The ceramic top offers high-impact strength, chemical resistance and a bright white color to enhance solution visibility. Stirrer speed can be adjusted from 200 to 2500 rpm. The heating elements are embedded in the top so there are no exposed or glowing heat sources. The hot plate will reach maximum temperature within eight minutes. Power indicator lights are provided for both functions. Includes a PTFE-coated stirring bar, three-wire grounded cord and plug. Integral ring-stand holder accommodates 1⁄2" diameter support rod (Catalog No. AP8228). 4" x 4": 120 volts, 3.5 amps, 405 watts. 7" x 7": 120 volts, 9.2 amps, 1086 watts.
Solubility Rules—Super Value Kit
Rather than memorizing solubility rules, students investigate 42 precipitation reac- tions combining sets of salt solutions, classify the substances, analyze patterns and develop their own general solubility rules from their observations. Includes detailed Teacher Notes and reproducible student handouts. Super Value Kit is complete for 5 classes of 30 students working in pairs.
