Polarity & Solubility of Benzoic acid

The question is whether C6H5COOH (Benzoic acid) soluble or insoluble in water? We'll also look at the polarity for the Benzoic acid molecule at well to help us understand whether it is soluble or insoluble. The answer is that C6H5COOH is not very soluble in water at normal temperature. It has a large nonpolar section of the molecule (the ring) which does not dissolve in water. At the same time it does have the polar carboxyl group -COOH that is polar and interacts with water. Because of this it's solubility at lower temperatures is limited (although it is more soluble in water at higher temperatures). Solubility of Benzoic acid (from https://en.wikipedia.org/wiki/Benzoic...) 1.7 g/L (0 °C) 2.7 g/L (18 °C) 3.44 g/L (25 °C) 5.51 g/L (40 °C) 21.45 g/L (75 °C) 56.31 g/L (100 °C) More Learning Resources • Polar and Non-Polar Tutorial:    • Polar, Non-Polar, and Ionic Compounds...   • Drawing Lewis Structures:    • Lewis Structures for Covalent Molecul...   • Determining Molecular Geometry:    • Molecular Geometry: Rules, Examples, ...   • Periodic Table with Electronegativity Values: https://en.wikipedia.org/wiki/Electro...

Exceptions Ag+, Pb2+, and (Hg2)2+ - most sulfates are soluble. Exceptions: Ba2+, Ca2+, Pb2+, Ag+, Sr2+ - most hydroxide salts are only slightly soluble. Exceptions: NH4+, Li+, Na+, K+ - most carbonates (CO32-) are insoluble. Exceptions: Group 1 and NH4+ Note: Rules at the top supersede any lower rules.
