Dude,

Ans. 1

Energy in both the test tubes will remain same, as both the springs are of same length and same spring constants. There is nothing to explain so elaborately. Here, the compression of spring cannot be taken into picture because the energy of the acid only depends upon the volume and the type of substance dissolved. The only change you will see is that the compressed spring will take more time to dissolve.

It is like dissolving one crystal of sugar in one test tube and one crushed crystal of sugar in another.
