Our chemist found a solution of 0.333M H3PO4 (phosphoric acid) and another of 1.05M NaOH (amazing what you can find in the belly of a ship) and so she did an enthalpy of neutralization reaction using 50.0mL of each solution. (Phosphoric acid is a triprotic acid; each mole of acid can yield 3 moles of H+ ions.) Using the CRC Handbook at hand, the density and specific heats of the final solution were found to be 1.11 g/mL and 3.81...

4. You mix 50.0 ml. of a weak monoprotic acid with 50.0 mL of NaOH solution in a coffee cup calorimeter. Both solutions and the calorimeter were initially at 22.8*C. The final temperature of the neutralization reaction was determined to be 41.2°C. The calorimeter constant was known to be 110.53/°C. Density Aqueous Solution - 1.00 g/mL Specific Heat of water = 4.184J/g•°C a. What is the total amount of heat evolved in this reaction? b. If 148 mmol of the...

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
