(Originais Teachy 2023) - Question Medium of Chemistry

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 1:


During a solubility experiment in the school laboratory, students were given a sample of potassium nitrate (KNO₃) to study how temperature affects its behavior in an aqueous solution. The table below shows the solubility coefficient of potassium nitrate as a function of temperature in degrees Celsius (ºC): | Temperature (ºC) | Solubility (g/100 g of water) | |-------------------|---------| | 0 | 13.3 | | 20 | 31.6 | | 40 | 64.0 | a) Calculate the maximum amount of potassium nitrate, in grams, that could be dissolved in 200 g of water at 20ºC. b) Suppose we have a KNO₃ solution with 60 g of solute dissolved in 100 g of water at 40ºC. When this solution is placed in an environment at 20ºC, what will be its solubility? Will there be any precipitate? c) If we obtain a saturated solution of KNO₃ at a temperature of 40ºC and then cool it to 0ºC, what will be the amount of solute, in grams, that will precipitate?

Question 2:


During a visit to a renowned Chemistry research laboratory, you, as a second-year high school student, had the opportunity to observe an experiment involving the dilution of a sample of hydrochloric acid (HCl). The researchers initially had an HCl solution with a concentration of 12 mol/L and, for the experiment, they needed a solution with a concentration of 3 mol/L. Considering that the researchers had a volume of 500 mL of the initial solution, what would be the appropriate procedures to obtain the desired solution and what would be the final volume of the solution after dilution?
