Using chemical equations, describe the reaction(s) that leads to the production of the citrate-stabilized gold nanoparticles. What are the products of the reaction, including the products of citrate oxidation? Note that you should indicate a disproportionation reaction somewhere. (What is a disproportionation?)
Homework Answers
Disproportionation means,it's a specific type of Redox Reaction in which an element form a reaction under goes both oxidation and reduction to form two different products

Question: Write the chemical reaction for the following experiment involving the synthesis of gold nanoparticles using Tea leaves as a reducing agent. Experiment Goal: The aim of this experiment is to synthesize gold nanoparticles of ~ 10-15nm size using Tea leaves as a reducing agent. Synthesis: Step 1: In a 20 ml vial, 0.012g of Gum Arabic was dissolved in 6ml of doubly ionized water D (I). Step 2: 100mg of Tea leaves (Lipton Loose Tea) was added to the...

Lawine six chemical equations describe the six reactions that you used to convert copper into compounds and ultimately reproduce the original copper sample. Consistent with the law of rvation of mass, determine if each of the given equations are balanced. Balance those that are unbalanced by including the appropriate coefficients. Reaction 1: Cu(s) + 4H*(aq) + 2NO;(aq) - Cu + (aq) + 2NO2(g) + H2O(l) Reaction 2: Cu?(aq) + OH(aq) - Cu(OH),(s) Reaction 3: Cu(OH),(s) - CuO(s) + 2H,0(1) Reaction...

Balanced chemical equations, which represent reactions, include coefficients that describe the ratio between the reactants and products. A balanced chemical equation not only describes how many molecules or moles react with each other, but it also embodies the fact that matter and mass are conserved in a reaction. This means that all of the atoms present among the reactants will be present in the same amount among the products. For example, the combustion reaction between methane and oxygen can be...

1-The rate constant of a chemical reaction was measured at several temperature values and a plot of ln k (on the y-axis) was plotted against 1/T (on the x-axis, temperature was measured in Kelvin). If the slope of the plot was -9.21 x 103 K and the y-intercept was 13.0, what is the activation energy (EA) of the reaction in kJ mol-1? 2-In an enzyme-catalyzed reaction, the rate of the reaction depends on which of the following at very low...

Microscale techniques: In today's experiment we will be using very small amounts of chemical reactants. This method is generally less expensive and more environmentally-friendly than traditional "test tube" chemistry. Some of the waste products produced in today's experiment, particularly those containing lead and barium, are harmful to the environment. By using such small amounts of chemical reactants we generate far less waste than by using larger scale methods. Procedure 1. Put on your safety goggles. Be sure to wear them...
