Question

Kinerics of the Oxidation of a Water Soluble Dye:

Explain and provide a written example about the kinetics of the oxidation reaction of blue dye (used as a food coloring) by common household bleach?

Answer 1

Common household liquid bleach is often a solution of sodium or calcium hypochlorite. Being a powerful oxidizing agent, the hypochlorite ion can decompose many organic substances.

bleach will used to decompose the commonly found in blue-colored beverages and snacks.

the relationship between the time it takes to completely – or nearly so –bleach the dye and the concentration of the bleach necessary to do so. There are several factors that affect the rate of a reaction, including concentration of reactants, surface area of a reactant in a heterogeneous reaction, temperature, pressure (if a reactant is a gas), and the presence of a catalyst. the chemical conditions necessary to achieve nearly complete decomposition of the dye . the rate law for the reaction

Dye + ClO -   ------------------> products

The generalform of the rate law for the reaction can be written

Rate = k[dye]^x[ClO-]^y

so from this rate also depends on dye concentration. like reactant concentration, temperature , pressure and catalyst.
