Brief Introductory Discussion. 2. a. All chlorides (Cl-) are soluble except AgCl, Hg 2 Cl 2, and PbCl 2 which are insoluble. Any substance that can form 0.1 M or more concentrated is soluble. The dividing line between soluble and insoluble is 0.1-molar at 25 °C. B) Ionic compounds are soluble in water. There is no "hard and fast" rule, but in general, solubility increases as the temperature increases. The most common definition for solubility is this: 1) Soluble substances can form a 0.10-molar solution at 25 °C. These are the general solubility rules for inorganic compounds, primarily inorganic salts. SOLUBILITY RULES. In chemistry, the “like dissolves like” rule refers to solubility and polar and non-polar substances. Learn vocabulary, terms, and more with flashcards, games, and other study tools.

SOLUBILITY RULES 1. Salts of ammonium (NH 4 +) and Group IA are always soluble. On the basis of the general solubility rules given in Table 7.1, predict which of the following substances are not likely to be soluble in water. The nonspecific mechanism of general anaesthetic action was first proposed by Von Bibra and Harless in 1847. They suggested that general anaesthetics may act by dissolving in the fatty fraction of brain cells and removing fatty constituents from them, thus changing activity of brain cells and inducing anaesthesia. Most of the precipitation reactions that we will deal with involve aqueous salt solutions. A Table for the Solubility of Salts in Water. A) Why does solubility depend on the number of cations and number of anions? For a general compound which doesn't show hydrogen bonding, its solubility should depend upon its percentage of ionic character. Each rule has exceptions and the important ones are noted. Start studying General solubility Rules. Indicate which specific rule(s) led to …

General Rules of Solubility. Generally Soluble Inorganic Compounds But there are clearly several exceptions to this. Comparison of percentage ionic and covalent character can be simply done using Fajan's rule. Remember: “Solute” means the substance that is dissolved into a larger substance (the solvent). b. All bromides (Br-) are soluble except AgBr, Hg 2 Br 2, HgBr 2, and PbBr 2 which are insoluble. Any substance that fails to reach 0.1 M is defined to be insoluble. Use the solubility rules to determine whether a compound will dissolve or precipitate in water. Asked in Science , Chemistry , Chemical Bonding These rules are general and qualitative in nature.
