28 Μαΐ 2024 · Write the chemical formula for the compound that is formed when aluminum and sulfur bond with one another. Solution. Based on the combinations listed in Section 3.2, these elements will combine to form an ionic compound, because aluminum, a metal, ionizes to form a cation (Al +3), and sulfur, a non-metal, ionizes to form an anion (S –2). The ...
It involves looking at the equation and adjusting the coefficients to get the same number of each type of atom on both sides of the equation. Best for: Simple equations with a small number of atoms. Process: Start with the most complex molecule or the one with the most elements, and adjust the coefficients of the reactants and products until ...
Experiment 4: Synthesis of Alum from Scrap Aluminum. Objective: In this experiment, you will be converting the aluminum metal from a beverage can into the chemical compound potassium aluminum sulfate, KAl(SO4)2•12 H2O, commonly referred to as alum.
You will synthesize potassium aluminum sulfate dodecahydrate, KAl (SO 4) 2 •12H 2 O by placing the appropriate ions in one container in aqueous solution and then evaporate the water to form the alum crystals. This particular compound has been chosen because it is relatively simple to prepare a pure sample.
Aluminum and carbon react to form an ionic compound. Predict which forms an anion, which forms a cation, and the charges of each ion. Write the symbol for each ion and name them.

Alums are ionic compounds that are made up of a monovalent cation (e.g., K+, Na+, NH4 +), a trivalent cation (e.g., A13+, Cr3+, Fe3+), two sulfate anions (SO4 2-), and twelve water molecules. In this experiment we will synthesize aluminum potassium sulfate dodecahydrate ( KAl(SO4)2 • 12 H2O ) from aluminum foil and other basic chemicals.
