Perchloric acid with an aqueos solution of ammonia and nitrous acid with lithium hydroxide
Constant-boiling HCl can be used as a primary standard for acid-base titrations. A 50.00 mL sample of constant-boiling HCl with a concentration of 0.1193 M was collected and titrated to an end point with 34.89 mL of Ba(OH)2 solution. What is the m..
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..
