Chapter 3 Calculation with Chemical Formulas and Equations
1 mol NaCl = 6 02 x 10 23 NaCl formula units Calculation: If 1 mole CaCl 2 = 6 02 x 10 23 CaCl 2 formula units, How many Cl – ions are in 1 mole of CaCl 2? 1 mole of CaCl 2 consists of 1 mole Ca 2+ and 2 mole Cl – If 1 mole of Cl – is 6 02 x 10 23 Cl – ions, then 1 mole of CaCl 2 contains (2 x 6 02 x 10 23) Cl – ions or 1 20 x 10 24
Calcium Analysis by EDTA Titration
Calcium Analysis by EDTA Titration One of the factors that establish the quality of a water supply is its degree of hardness The hardness of water is defined in terms of its content of calcium and magnesium ions Since an analysis does not distinguish between Ca2+ and Mg2+, and since most hardness is caused by
Ion Exchange for Dummies - Lenntech
You need 2 chloride anions to balance each calcium cation Therefore the formula of calcium chloride is CaCl2 Similarly, in sodium carbonate you have sodium cations Na+ and carbonate anions CO 3 =, so that you need 2 sodium ions for each carbonate ion, and the formula is Na2CO3

Calcium Phosphide Polyatomic ions are ions formed by more than one atom Below are some common polyatomic ions along with their oxidation numbers: • (SO 4)-2 Sulfate • (PO 4)-3 Phosphate • (NO )-1 Nitrate • (NH 4)+1 Ammonium Determine the chemical compound formula and compound name for the compounds made with these combinations:
FORMULA WRITING AND NOMENCLATURE OF INORGANIC COMPOUNDS
ion the formula of the polyatomic ion must be placed in parentheses if the subscript is two or larger This will indicate that the subscript applies to all the elements within the parentheses The correct formula for calcium acetate is: Ca(C2H3O2)2 The algebraic sum of the oxidation numbers is +2 + [2 x (-1)] = 0
