Question 8 (2 points) A 6.5-ml sample of a 0.11 M HCl(aq) solution was mixed with a 4.1-mL sample of a 0.70 M HCl(aq) solution. Calculate the pH of the mixture. Provide your answer to the correct number of decimal places. Your Answer: Answer Hide hint for Question 8 There is no reaction. You are simply mixing two solutions of the same acid. First calculate the molarity of the mixture and finally the pH of the mixture.
Question 7 (2 points) A 3.0-ml sample of a 0.10 M HCl(aq) solution was mixed with a 4.8-mL sample of a 0.63 M HCl(aq) solution. Calculate the pH of the mixture. Provide your answer to the correct number of decimal places.
HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(1) 100.0 mL of 0.500 M HCl is mixed with 300.0 mL of 0.100 M NaOH in a coffee cup calorimeter. Assuming the temperature of the solution was initially 25.0 °C, and the final temperature of the solution was 26.7 °C, calculate the enthalpy of this reaction per mole of HCl. Assume the density of the water and acid and base solutions are all 1.00 g/mL.
