A solution of the weak acid, HF, and a solution of the strong acid, HCl, have the same pH. Which solution will require the most sodium hydroxide, NaOH, to neutralize?
A) HCl because it is a strong acid and dissociates completely.
B) HF because its concentration is larger.
C) Both will require the same amount because the concentrations are equal.
D) Both will require the same amount because the H3O+ concentrations are the same.
E) HCl because the stronger acid has the higher concentration.
An environmental engineer analyzes a sample of air contaminated with sulfur dioxide. To a 500m mL sample of air at 700 torr and 38 degrees celsius, she adds 20.00 mL of 0.01017 M aqueous iodine, which reacts as follows
A student mixed 50.0 mL of 0.50 M H2SO4 (aq) at 18.5 degrees C with 100 mL of 0.50 M NaOH (aq) at the same temperature. After the reaction was completed, the temperature rose to 22.0 degrees C. What was the heat of reaction? (Assuming the densitie..
