  • Net Ionic Equation Worksheet Answers
    Honors Chemistry Name__________________________________ Period_____ Net Ionic Equation Worksheet READ THIS: When two solutions of ionic compounds are mixed, a solid may form. This type of reaction is called a precipitation reaction, and the solid produced in the reaction is known as the precipitate. You can predict whether a precipitate will form using a list of solubility rules such as those found in the table below. When a combination of ions is described as insoluble, a precipitate forms. There are three types of equations that are commonly written to describe a precipitation reaction. The molecular equation shows each of the substances in the reaction as compounds with physical states written next to the chemical formulas. The complete ionic equation shows each of the aqueous compounds as separate ions. Insoluble substances are not separated and these have the symbol (s) written next to them. Water is also not separated and it has a (l) written next to it. Notice that there are ions that are present on both sides of the reaction arrow –> that is, they do not react. These ions are known as spectator ions and they are eliminated from complete ionic equation by crossing them out. The remaining equation is known as the net ionic equation. For example: The reaction of potassium chloride and lead II nitrate Molecular Equation: 2KCl (aq) + Pb(NO3)2 (aq) -> 2KNO3 (aq) + PbCl2 (s) + - 2+ 3– + – Complete Ionic Equation: 2K (aq) + 2Cl (aq) + Pb (aq) + 2NO (aq) -> 2K (aq) + 2NO3 (aq) + PbCl2 (s) - 2+ Net Ionic Equation: 2Cl (aq) + Pb (aq) -> PbCl2 (s) Directions: Write balanced molecular, ionic, and net ionic equations for each of the following reactions.

    Sodium sulfate - Wikipedia, the free encyclopedia Page 1 of 7 Sodium sulfate From Wikipedia, the free encyclopedia Sodium sulfate is the sodium salt of Sodium sulfate sulfuric acid. When anhydrous, it is a white crystalline solid of formula Na2SO4 known as the mineral thenardite; the decahydrate Na2SO4·10H2O has been known as Glauber's salt or, historically, sal mirabilis since the 17th century. Another Other names solid is the heptahydrate, which transforms Thenardite (mineral) to mirabilite when cooled. With an annual Glauber's salt (decahydrate) production of 6 million tonnes, it is a major Sal mirabilis (decahydrate) commodity chemical and one of the most Mirabilite (decahydrate) damaging salts in structure conservation: when it grows in the pores of stones it can Identifiers achieve high levels of pressure, causing CAS number 7757-82-6 , structures to crack. 7727-73-3 (decahydrate) Sodium sulfate is mainly used for the PubChem 24436 manufacture of detergents and in the Kraft ChemSpider 22844 process of paper pulping.
