Qualitative Analysis: Identifying Anions and Cations

 · Updated November 04, 2019. Qualitative analysis is used to identify and separate cations and anions in a sample substance. Unlike quantitative analysis, which seeks to determine the quantity or amount of sample, qualitative analysis is a descriptive form of analysis. In an educational setting, the concentrations of the ions to be identified are ...

Molarity of Ions Example Problem

 · This example problem demonstrates how to calculate the molarity of ions in an aqueous solution. Molarity is a concentration in terms of moles per liter of solution. Because an ionic compound dissociates into its components cations and anions in solution, the key to the problem is identifying how many moles of ions are produced during dissolution.

Specific binding of trivalent metal ions to λ-carrageenan

 · In this work, the interaction and binding behavior between λ -car and metal ions of different valency (Na +, K +, Mg 2+, Ca 2+, Fe 2+, Fe 3+, Al 3+, Cr 3+) have been investigated. In contrast to the non-specific interaction of the monovalent and divalent cations, specific binding has been identified between λ -car and Fe 3+ /Al 3+.

How to interpret a Solubility Table? We can use the Solubility Table to determine whether an ionic compound exist as ions in aqueous solution (soluble) or as a solid (insoluble). Once we know the compound we use the Solubility Table to determine its solubility. For example, consider the following compounds; NaCl, BaSO 4, NaC 2 H 3 O 2, and CaS.

Elements and Compounds | Introduction to Chemistry

When two distinct elements are chemically combined—i.e., chemical bonds form between their atoms—the result is called a chemical compound. Most elements on Earth bond with other elements to form chemical compounds, such as sodium (Na) and Chloride (Cl), which combine to form table salt (NaCl). Water is another example of a chemical compound.
