Dissolution in porous media is a complex phenomenon. In most of the approaches, density variations are ignored but they generate important convection structures like those presented in [5]. In this chapter, our aim is to develop an experimental approach in order to validate our numerical tool. To do so, we will make use of local measurments using microtomography in order to get the surface evolution of the dissolved medium. We will also get some results about the weight losses of salt dissolved and then try to compare to those predicted by numerical simulations.
