The answer to this actually depends on how you define an acid and a base. Anhydrous copper(II) sulfate is copper(II) sulfate that is completely dry. That is, while element masses differ, when it comes to bonding with other atoms, the number of atoms, expressed in moles, is the determining factor in how much of a given element or compound will react with a given mass of another. g. So, in aqueous solution, the Cu2+ ions undergo hydrolysis as follows: Cu (2+) + H2O = CuOH (+) + H (+) The release of H+ ions by hydrolysis makes the solution distinctly acidic. Like acid-base reactions, redox reactions are a matched set -- you don't have an oxidation reaction without a reduction reaction happening at the same time. If you increase the temperature of the reactants, you increase the kinetic energy of the particles. g. 2 ACIDS, BASES AND SALTS Acids combine with bases to form salts and water molecules. The most common method to get an idea about the pH of solution is to use an acid base indicator. 461 g; sulfuric acid (H 2 SO 4), 98. ZnCl2 is a Lewis acid because of the following reasons Zn+2 is a Lewis acid the chlorine does not hydrolyze so the equation would be like this ["Zn"("H"_ 2"O")_ 6]_ ((aq))^(2+) + "H"_ 2"O"_ ((l)) rightleftharpoons ["Zn"("H"_ 2"O")_ 5("OH")]_ ((aq))^(+) + "H"_ 3"O"_ ((aq))^(+) H_3O^+ indicates that something is acidic Another way to determine ZnCl2 is acidic is this ZnCl_2 + 2H_2O = Zn(OH)_2 Amino acids are generally classified by the properties of their side chain into four groups. 75 B- 249. pH Chemistry.
