Question 1:


During a practical Chemistry class in a school laboratory, the students received two solutions of copper sulfate (CuSO4), each with different concentrations. Solution A contains 250 mL with a concentration of 0.8 mol/L and solution B contains 350 mL with a concentration of 1.2 mol/L. If solutions A and B are combined in a single container, what will be the resulting concentration of the mixture?

Question 2:


During a laboratory experiment, a student mixes two solutions containing the same solute, sulfuric acid (H2SO4). The first solution has a volume of 200 mL and a concentration of 0.5 mol/L, while the second solution has a volume of 400 mL and a concentration of 0.2 mol/L. (a) Calculate the amount in moles of sulfuric acid present in each solution before mixing. (b) After mixing the two solutions, determine the final concentration of sulfuric acid in the mixture. (c) Evaluate whether the final concentration obtained indicates a more or less concentrated solution than the initial solutions.

Question 4:


During a practical Chemistry class, the students received an aqueous solution of copper sulfate (CuSO4) and were challenged to perform the electrolysis of this solution. First, determine what happens at the cathode and anode during the electrolysis of copper sulfate. After that, calculate the amount of copper (in grams) deposited at the cathode after a current of 0.5 A passes through for one hour. Consider the deposition process to be 100% efficient. Finally, explain other practical applications of electrolysis in our daily lives.
