Electrolysis is an electrochemical process in which current flows from one electrode to the next in an ionised electrolyte solution. DOI: 10.1595/147106708X255987), and where do you draw the line between a "physical" electrostatic interaction (in, say, $\ce{Na(OH_2)_6^+}$) and a chemical bond (as seen in $\ce{Cr(OH_2)_6^3+}$? Unfortunately, this is wrong. Create an equation for each element (Na, O, H, Cu, S) where each term represents the number of atoms of the element in each reactant or product. So you will never be able to obtain a $0.1$ M solution of $\ce{CuSO4}$ at pH $5$ or $6$. Since there is an equal number of each element in the reactants and products of 2Fe + 3CuSO4 = Fe2(SO4)3 + 3Cu, the equation is balanced. Your major problem is you are using way too high concentration of your $\ce{Cu^2+}$ solution. I heated it in the lab just until it turned white, This misses the point of the question. To decide which reaction will be occurred, standard potential values of each half reaction are considered. pH 6. Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. Did the Golden Gate Bridge 'flatten' under the weight of 300,000 people in 1987? Interpreting non-statistically significant results: Do we have "no evidence" or "insufficient evidence" to reject the null? Positively charged ions move to the negative electrode (the cathode), and negatively charged ions move to the positive electrode (the anode). Cross out the spectator ions on both sides of complete ionic equation.5. Does the 500-table limit still apply to the latest version of Cassandra? If S > 0, it is endoentropic. Zinc + Cupric Sulfate = Copper + Zinc Sulfate, S(products) > S(reactants), so Zn + CuSO4 = Cu + ZnSO4 is, G(reactants) > G(products), so Zn + CuSO4 = Cu + ZnSO4 is, (assuming all reactants and products are aqueous. Moreover, there is no new substance being formed and so it is a physical change. Thermodynamics of the reaction can be calculated using a lookup table.
