Temp of HCl before mixing = ------- Temp of NaOH before mixing = ---------- Highest temp reached after mixing = ------- temp rise = ------------ Mass of solution = ---------- Heat librated = M*C*(T2-T1)
In this experiment, a known number of moles of Hydrochloric acid is mixed with an equal number of moles of Sodium hydroxide in an insulated container.
1. A 50-centimeter cubed of the 1-mole hydrochloric acid solution into one of the plastic cup
2. using a second graduated cylinder place a 50-centimeter cubed of 1 molar sodium hydroxide solution into the second plastic cup
3. measure the temp of the hydrochloric acid solution which is 21.8 c
4. measure the temperature of the sodium hydroxide solution which is 21.7 c
5. when both solutions are at the same room temp, stir well and avoid any loss of liquid and splashing
6. place a lid onto the plastic cup and continue stirring. Record the maximum temp reached. which is 24.5 C
Now find
Temp of HCl before mixing = -------
Temp of NaOH before mixing = ----------
Highest temp reached after mixing = -------
temp rise = ------------
Mass of solution = ----------
Heat librated = M*C*(T2-T1)
