Write answers in academic format and at least 1 paragraph for each answer. Answer all questions using this reaction of a dark blue solution of zinc Il ions being mixed with a chlorate ion solution that has a yellow color. When equilibrium is reached they form a green solution and also have the presence of a white crystalline solid of zinc Il chlorate.
In this case the precipitate does dissociate as part of the equilibrium reaction.
Zn^2+ Plus ClO31 <—->
1. Write the correct formula for the product
2. Write correct physical states for all reactants and products.
3. Balance the equation showing all work.
4. If colorless Na+ ion solution is added to the reaction after equilibrium is reached what shift will occur and why? (need to explain all interactions)
5. What color change will be observed?
6. What is the formula for a chlorite ion and explain how it differs from chlorate?
Question 2– Explain two properties of an equilibrium reaction system that are equal when equilibrium has been reached.
Question 3 -
Explain two properties of an equilibrium reaction system that are not certainly equal when equilibrium has been reached.
1. The correct formula for the product formed when a dark blue solution of zinc II ions is mixed with a chlorate ion solution is Zn(ClO3)2.
2. The physical states of the reactants and products in this chemical reaction are as follows:
Reactants:
- Zinc II ions (Zn^2+): aqueous
- Chlorate ions (ClO3^-): aqueous
Products:
- Zinc II chlorate (Zn(ClO3)2): white crystalline solid
- Green solution
3. The balanced equation for the reaction is as follows:
Zn^2+ (aq) + 2 ClO3^- (aq) <—-> Zn(ClO3)2 (s)
4. When colorless Na+ ion solution is added to the reaction after equilibrium is reached, the equilibrium will shift to the left. This is because the addition of Na+ ions (a common ion) will lead to the common ion effect, decreasing the solubility of zinc II chlorate and causing more of the white crystalline solid to form. The Le Chatelier's principle can also be applied here, where the system will try to counteract the added Na+ ions by shifting the equilibrium to the left.
5. The color change observed when colorless Na+ ion solution is added to the reaction after equilibrium is reached will be a more pronounced formation of the white crystalline solid of zinc II chlorate. This will result in a decrease in the green color of the solution and an increase in the presence of the white solid.
6. The formula for a chlorite ion is ClO2^-1. The main difference between chlorite and chlorate ions lies in their oxygen content: chlorite ions contain two oxygen atoms (ClO2^-1), while chlorate ions contain three oxygen atoms (ClO3^-). This difference in composition leads to variations in their chemical behaviors and properties.
Question 2: Two properties of an equilibrium reaction system that are equal when equilibrium has been reached are the rates of the forward and reverse reactions, and the concentrations of the reactants and products remain constant.
Question 3: Two properties of an equilibrium reaction system that are not necessarily equal when equilibrium has been reached are the rates of the forward and reverse reactions (they may not be exactly equal), and the extent of the reactants and products present in the system may not be at equilibrium concentrations.
