Cake alum (aluminum sulfate) is used as a flocculatingagentin water purification. The “floc” is a gelatinous precipitate of aluminum hydroxide that carries small suspended particles and bacteria out of solution for removal by filtration.(a) The hydroxide is formed by the reaction of the aluminum ion with water. Write the equation for this reaction.(b) The acidity from this reaction is partially neutralized by the sulfate ion. Write an equation for this reaction.
A solution is prepared by dissolving 2.95 g Co2(SO4)3 in enough water to make 1.00 L of red solution; the red color is due to the presence of the cobalt ions. To this solution was added 1.52 g of magnesium powder. A redox reaction occurred, in which the magnesium atoms lose all of their valence electrons and the red color of the solution fades.
(a) Write the total reaction that occurs and the net ionic equation for the redox process. (Assume that one of the products of the redox reaction is a metal.)
(b) Calculate the initial concentration of cobalt ions, the final concentration of cobalt ions, and the final concentration of magnesium ions.
Consider the following balanced redox reaction:2CrO₂⁻(aq) +2H₂O(l)+6ClO⁻(aq)→ 2CrO₄²⁻(aq) +3Cl₂(g) +4OH⁻(aq)(a) Which species is being oxidized?(b) Which species is being reduced?(c) Which species is the oxidizing agent?(d) Which species is the reducing agent?(e) From which species to which does electron transfer occur?(f) Write the balanced molecular equation, with Naas the spec-tator ion.
