This is a question from a lab previously done for my chem class.
If you had used 40 mL of water and 6 g of ammonium chloride, rather than the 20 mL and 3g in the experiment, would you expect to get a larger, smaller, or identical temperature change?
In the experiment I dissolved 3g in 20 mL and the temperature dropped 10.7*. Now, I understand there is an endothermic reaction and it is caused by the lattice energy from the breaking of ionic bonds, but I'm not sure how it is affected when BOTH are doubled. Being both water and ammonium chloride.
Seems to me though more water would result in a smaller temp drop, and more ammonium chloride would result in a larger temp drop, so being that both are involved, the temp change would remain the same?
Though that's what my intuition tells me, I am not convinced since I really have no "details" to back up what I think.
Any input??
Thanks.
