Nomenclature for Ionic Compounds Ionic compounds consist of cations (positive ions) and anions (negative ions). The nomenclature‚ or naming‚ of ionic compounds is based on the names of the component ions. Here are the principal naming conventions for ionic compounds‚ along with examples to show how they are used: Roman NumeralsA Roman numeral in parentheses‚ followed by the name of the element‚ is used for elements that can form more than one positive ion. This is usually seen with metals. You

The General Agreement on Tariffs and Trade (GATT) 1947 functioned as a means of adjusting trade relationships between countries trying to improve their economies. Contracting parties to this agreement have been bound by it to treat other contracting parties on an equal and reciprocal basis as well as to curb protectionism. At the start of 1995‚ the GATT has been succeeded by the World Trade Organization (WTO) and has since been the most important development in international trade. However‚ it is

Chromatography • • • Separation based on polarity of compounds Two potential phases for a compound to exist in: mobile and stationary Partitioning of compounds between mobile phase and stationary phase occurs: o Compounds that are less polar move more in the mobile phase‚ those that are more polar “stick” more on the stationary phase o These polarity differences cause compounds move at different rates and therefore can be separated 1. Mobile Phase: the phase the moves; can be gas or
